Video Transcript for Review of Ultra-Fab Products RV and Camper Hitch - RV Bumper Mount Hitch - UF35-946402
Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Ultra-Fab two inch Motor Home Trailer Hitch Receiver for four inch by four inch steel bumpers, has a 3,500 pound gross towing weight capacity. Now, this powder coated steel hitch receiver is designed to clamp around your RV's four inch square bumper, and it provides this two inch receiver opening for your hitch mounted accessories such as bike racks, cargo carriers, or you can even use it for light towing. Now, this hitch receiver can only be mounted onto a four inch square continuous steel welded bumper, it's not designed for aluminum bumpers. This is a heavy-duty steel construction, does have a maximum gross trailer weight capacity of 3,500 pounds. Now, one note on that is you do not wanna exceed the weight rating of the bumper it attaches to, and it has a maximum tongue weight of 100 pounds.
If you noticed, if I show you the bottom of it, you can see it does have the safety loops on each side for connecting your safety chains to. We mentioned the black powder coat finish on it, provides rust and corrosion resistance, and this is a nice bolt-on installation, it includes all the mounting hardware, you can see I've pretty much installed it onto the part just to show you where it all goes, and it comes with a nice set of instructions that'll describe how it all goes together. Now, also I wanted to show you, if you look closely, right here and right at the very bottom, there's two large bolts here, these thread into the hitch receiver, and the reason those are on there is once you put your accessory in there, you tighten those down on the bottom and on the side, and it'll help reduce movement between the hitch mount and the receiver tube. Again, the application, you can see the U-bolts here, they are designed to fit four inch by four inch continuous steel welded RV bumpers. Receiver opening right up here is two inches by two inches, and one note is this is designed for use with RV approved accessories only.
Let me show you all the sides. But that should do it for the review on the Ultra-Fab two inch Motor Home Trailer Hitch Receiver for four inch by four inch steel bumpers.

This powder coated steel receiver clamps around your RV's 4" square bumper to provide a 2" x 2" trailer hitch receiver opening. Perfect for hitch accessories or light-duty towing.by: Mark N09/11/2018
Installed this hitch on my fifth wheel to pull my side by side to the upper peninsula in Michigan, however I would recommend that you be sure your bumper is capable of the weight being towed. I personally removed my existing bumper and welded on a much heavier steel bumper. This hitch did exactly what was expected of it, thanks so much to Kirstin for her help at checkout
by: Alan08/01/2023
hooked up hitch both u bolts broke dropping both bicycles on freeway in Montana. Just a fact and no total rack and bikes were well un der the maximum load rateing,
by: Old Woman Camping06/19/2022
Product fit perfect. Easy to install. Very happy with the hitch, Only one problem, the anti-wobble bolt on the side would not fit because U-bolt is in the way. You can only get the bottom anti-wobble bolt in. (See 2 pictures) I solved that problem by cutting off the end of the U-bolt that was in the way. They just need to move that hole back a bit more. Now I have both bolts on and cargo carrier is solid.
by: Kenneth06/04/2021
This fit very well, only problem is the side anti wobble bolt won’t fit when the U bolts are installed. Note submitted picture.

Just ground off a 12 inch or so, installed bolt before the U bolt. Works fine now.
by: Steve Cosgriff02/26/2020
This bracket provided me the means to mount the receiver style spare tire b racket on my Class C RV. By mounting it upside down, it placed the weight squarely on the frame, leaving the u-bolts to merely hold it in place.
by: William12/06/2017
Works great used on trailer bumber for portable refrigerator to carry on cargo unit. Had to beef up bumper with angle iron due to weight ...no bounce at all with hitch
by: James DaVanzo08/26/2013
The product arrived ahead of schedule. etrailer upgraded my shipping at no extra cost! It fit on my bumper with very little problem. It was tight because of my chrome covering, but I expected that. I did have to replace two of the nuts that would screw on, and I had wanted to place it above the bumper but the body of the trailer wouldn't let me. I haven't gotten a bike carrier yet, but I wholly expect it to work just fine. I would have given it an excellent but for the bolts I had to replace.
by: Norman 09/07/2023
Works as advertised. Simple to attach. I use it on the back of my camper an put a generator, extra fuel and loaded cooler. Thanks for great product.
by: Zachary08/20/2020
Cold the cargo rack on the rear of our travel trailer.I bought it so that I can lock my generator to it when we’re traveling.
by: Roger04/29/2021
This bolt on hitch worked as advertised. Important to get the bolts sufficiently tight. I used this product to hold a cargo carrier on 2020 Colorado camping trip.
by: Scott S.10/07/2020
I needed a way to carry our mountain bikes when we go traveling with a our RV. The Ultra-Fab Hitch receiver fit perfectly on the 4x4 rear bumper allowing me to carry our bike rack. I feel I could even tow my golf cart trailer behind my RV with this hitch if needed. Very easy to install with a simple socket set and torque wrench.
by: Bryan05/29/2019
Very easy to install (my four year old helped me). We used it for our bike rack on the back of the trailer so it was installed on top of the bumper instead of underneath. This thing holds it very solid.
by: Bret07/31/2018
Product looks and feels very solid and well made. Only took me 5 mins to install. Can't wait to see how it performs as we head out in the next few days. I will be carrying my generators and gas and kids bikes on it. Thank you again etrailer.com for an easy purchase with all of the info i could ask for on your website to help make the best selection for my needs.

by: Jesus07/29/2022
The bolts on the top are not long enough. I had to buy longer bolts. The bolt on the side that secures the hitch to reduce the movement is too long. The u-bolt is in the way. I had to buy a shorter bolt. The bolt hole needs to be repositioned so the u-bolt will not interfere.
by: Paul P.04/22/2015
Well constructed, very easy to install, negates fabricating or adapting a hitch by taking advantage of existing 4" bumper.
by: David 06/08/2023
E trailer is a consistent place I shop for fast delivery, great communication and products as described.
by: Starr08/22/2022
Will not slide properly over my 2” hitch, machined wrong, the holes for the hitched pin indent in on the hitch, will not work. This is my second try, I wish they would inspect there products before sending them out as I am stuck with no way to move.. will be asking for a full refund.very disappointed!!

This is for mounting on motorhome bumpers not to mount on hitch receiver bars.
by: enduser10/08/2019
Bought (2) of them to make to make a removable rack for a small inflatable boat to carry on the back of the trailer bumper. Appears plenty strong have to see how it lasts. Did notice that the chain loops interfere with the 5/8" bent hitch pin hair pin connection. I'll have to make one out of a bolt (they should have though of that).
Victoria B.

Rather than a bolt, I recommend using a straight hitch pin, such as the etrailer Trailer Hitch Lock # e98882. This hitch pin has a locking end cap to keep your hitch accessory secure. The lock core is accessed on the end of the cap, making it easier to access in a hitch with limited space like this one.

So far it was very easy to put on the Trailer, I used it for a cargo carrier to place a 3000 Honda Generator on the carrier, work great, the next thing I'm going to try is to pull my 2 Waverunners, but I will check the weight first..

It has worked great, but now I have changed my Trailer and do not need it anymore
by: Ron C.04/14/2017
The Ultra fab 2" RV Hitch Receiver for 4"x4" Bumpers is a very well made piece of steel. It fits our Wildwood Trailer Bumper perfectly. It is built so sturdy we have no worries about using it to haul our bicycles. It is rated at 3.5k!

Thanks for the review Ron, but please also keep in mind that an RV approved bike rack should be used, and please make sure the bumper is appropriately for your use.
by: Dave P03/24/2020
I mounted 2 on my camper bumper. One for a bike rack and the other for a swing away grill. Super happy w the product and the results.

A year later, I couldn’t imagine not having the bikes and the grill on the back of the RV. Great product
by: Robert G.12/01/2017
Very sturdy attachment. Fit perfectly on the trailer bumper and hardware was 1/2" Grade 8 Cad plated--good stuff. Order was received at my driveway exactly on schedule. I would continue to do business with etrailer.

The attachment is working great. I need to store it outside and see no physical deterioration.
by: Paul R07/14/2022
The top bolts were half inch to short. I had to go buy longer ones that cost $x.xx then only one of my hitch shanks will go far enough in to line up the holes for the pin.

- Recommended Trailer Hitch Receiver for 5th-Wheel TrailerWe have a nice selection of trailer hitches that are designed to be installed on RVs and fifth wheel trailers. If you are just wanting a hitch receiver to use with hitch-mounted accessories such as a bike rack or cargo carrier, I recommend looking at the Ultra-Fab 2 Inch Motor Home Trailer Hitch Receiver # UF35-946402. This will clamp around 4 inch x 4 inch square bumpers to provide a 2 inch receiver opening with a tongue weight capacity of 350 pounds. For 4-1/2 inch x 4 inch bumpers,...
view full answer... - Hitch and Bike Rack Rrecommendation for Coleman Lantern 17FQAs long as the 4-inch bumper you have on your Coleman Lantern 17FQ is fully boxed on all sides and is connected directly to the frame of the camper you should be fine, but you'd want to check with Coleman to see if they have a hitch capacity for the vehicle. If so, then the Ultra Fab bumper hitch part # UF35-946402 would be a great option for a bike rack. You'll need a bike rack confirmed for the rougher ride quality at the rear of a camper though. For that we have the Swagman E-Spec...

- Spare-Tire-Mount Bike Rack for Use on Rear of 2014 Aliner Scout Travel TrailerThank you for providing a photo of your Aliner's spare tire mount on its rear bumper. Any bike rack designed for use on the rear of a camper or trailer has to be specially built to withstand the forces encountered at the rear of such vehicles. Much in the same way that the last seat in a school bus or the last car in a roller coaster gets a rougher ride than those up front, any accessory item installed at the rear of a trailer will be subjected to strong lateral and vertical forces that...

- What is the Weight Limit on Ultra-Fab 2 Inch Motor Home Trailer Hitch ReceiverThe Ultra-Fab Motor Home Trailer Hitch Receiver, # UF35-946401, was designed with the RV/trailer application in mind. As such the additional torque from accessories bouncing in the receiver was taken into account when the weight capacity of 200 pounds was given to the hitch. You might want to consider going with something rated a little higher, like # E-100, or # UF35-946402, which both have a 350 pound capacity, because with your intended load you will be getting close to the tongue...
view full answer... - Best Option for Bolt On Receiver and 3 Bike Rack on Rear of Jayflight Travel TrailerThe Ultra-Fab Bolt On receiver you mentioned, part # UF35-946402 would be a good choice. The receiver tube has a tongue weight capacity of 350 lbs, which means that the combined weight of the bikes plus that of the bike rack you use shouldn't exceed 350 lbs. Before installing the hitch, I'd highly recommend you consult the owner's manual or Jayco to determine if the bumper has the proper capacity. If the capacity of the bumper is lower than that of the receiver, you'll be limited to the...
view full answer... - Bumper-Mounted Bike Rack Recommendation for 2016 Coleman Travel Trailer with 4 Inch BumperWe have a couple of options for a bike rack that will install on the 4 inch square bumper at the back of your Coleman Travel Trailer. Since you mentioned that your camper has a spare tire already installed on the bumper, a great bike rack option for you is the Swagman Around the Spare Deluxe 2-Bike Rack # S80501. One of my co-workers uses this bike rack on his trailer to carry his family's bikes when they go camping and he really likes it. This bike rack will install around the 4 inch...
view full answer... - Bumper Mounted Hitch That Will Work With Roadmaster Hitch Mounted Spare Tire CarrierThere is a hitch that will work for you, but the Bumper Hitch Receiver # S64025 that you referenced is for use with bike racks and would not be a fit for your new Roadmaster Spare Tire Mount RM-195225. Instead, I recommend the Ultra-Fab # UF35-946402 which is a 2" trailer hitch receiver that clamps onto 4" x 4" square bumpers and has a maximum tongue weight of 350 lbs, which should be well within the range of the Spare Tire Mount and spare tire. I've added links to a pair of video reviews...
view full answer... - Bumper Mounted Hitch Recommendation for RV to Carry a 75 lb Spare TireThe Swagman Specialty Trailer Hitch # S64025 that you referenced has a 200 lb capacity so it would be strong enough to handle the weight of your spare tire, but it is designed only for use with bike racks so although it would seem to work for you, I cannot recommend it for you. For a similar hitch that would work for what you are trying to do you would want the part # UF35-946402 . For a spare tire carrier you would then want the # C31006 as it would also have a high enough capacity for...
view full answer... - Need a Platform Style Bike Rack for Travel Trailer to Haul Heavy BikeWe do not currently have available a platform style bike rack that is rated for being used on a travel trailer. Due to suspension design, there is a rougher ride with travel trailers than passenger vehicles that have better developed suspension systems. Add to this the fact that travel trailers are towed, allowing sway from connection point, you need a more durable bike rack to withstand the torque and movement applied when loaded with a bike(s). There is a fairly wide selection of...

- Can Ultra-Fab Motor Home Hitch # UF35-946402 Be Used To Tow a Trailer Behind a Fifth WheelThe RV hitches like the Ultra-Fab 2 Inch Motor Home Trailer Hitch, part # UF35-946402, are designed to be used on the back of an RV to haul bike racks and cargo carriers. This hitch is one of the only ones that says for light-duty towing also. It states a 350-lb maximum tongue weight capacity, but you will want to make sure not to exceed the weight capacity of your fifth wheel bumper. We do not recommend towing two trailers because the tongue weight of the second trailer will be applied...

My suggestion is to consider the Trailer Valet XL Trailer Dolly with Chain Drive with 2" Hitch Ball, # TVXL2 or if needed, 2-5/16" ball in # TVXL25. This heavy-duty dolly with integrated drive will help you maneuver your trailer into...

It's great for light duty towing and will have a maximum gross trailer weight of 3,500 pounds. I recommend contacting your trailer manufacturer to see if your bumper is rated for towing. If you don't have a bumper, no worries because you can still add a trailer hitch to your frame. The most popular one we currently offer is the Curt adjustable width trailer...

view full answer... - RV-Rated Bike Rack Recommendations for Class A MotorhomeA hitch extension would seem to be the ideal solution for your circumstances with insufficient bike clearance at the back of your RV, but any type of extension like # C45791 will cost you half of your hitch capacity. Hitch adapters/extenders cause this loss of capacity because they change the geometry of the system, allowing for more stress to be applied to the hitch tube because the actual load is further away. A better option is an RV-rated bike rack that provides enough clearance without...

We have several options for you, such as the Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" Bumpers, # UF35-946402. This clamps around your RV's 4" square bumper to provide a receiver opening for hitch-mounted accessories - such as your bike rack. Although this must be a bike approved for use on a travel trailer. My recommendation is to consider the Jack-It 2 Bike Rack for A-Frame Trailers, # LC429756. This bike rack mounts on the...
view full answer... - Recommended Motorcycle/Scooter Carrier With Hitch Receiver For MotorhomeYou do not need a bumper to add a hitch and carrier for your scooter. I recommend the Adjustable Width Trailer Hitch Receiver for RVs, 18" to 51" Wide # C13702 or the # UF35-946403 which adjusts from 47-1/8 to 77 inches. Either of these hitch receivers will mount to your motorhome frame so a bumper is not needed. This can be used with thetrailer Motorcycle Carrier for 2" Hitches - 500 lbs # e98873 for your scooter. I recommend the Motorcycle Soft Loops # 06303 along with the Erickson...
view full answer... - Trailer Hitch and Spare Tire Carrier that Can fit 4 inch Square Bumper and Rear of CamperThe hitch I would recommend for fitting on a 4 by 4 inch bumper like what your RV has is the Ultra Fab part # UF35-946402 as it has a higher 350 lb tongue weight capacity than the Swagman you mentioned. Then the Curt spare tire carrier part # C31006 would fit and work well.

- Compatibility of Frame-Mount 2-Inch Trailer Hitch Receiver with Trailer Frame Over 73-Inches WideThe Curt Adjustable Width Trailer Hitch Receiver # 13703 will fit on RV and trailer frames whose outside-to-outside frame width measurement is from 22- to 72-inches. If your frame's INSIDE measurement is 73-inches then this hitch will not be wide enough to fit to the outsides of the frame rails as intended by Curt. Of all the frame-mount RV hitches we offer (see the linked page, please) this particular unit from Curt offers the widest possible dimension. We also offer bolt-on bumper-mount...
view full answer... - Trailer Hitch Recommendation for Carrying a Bike Rack on a TrailerThe Ultra-Fab bumper mount hitch # UF35-946402 is designed specifically for 4 inch x 4 inch square steel bumpers that are continuous welded. A slightly larger bumper will not be compatible. If by trimming the trim piece the bumper is still structurally sound and is 4 x 4 inches, it would fit. The best thing to do, if you are concerned with providing the safest and best ride for your bikes is to use a frame mounted trailer hitch, see link. The most popular option is # 13703. I have included...

The E-100 you mention is intended for use with 4 inch square bumpers, as well as the Ultra-Fab # UF35-946402. If you have clearance problems at the rear of the bumper, the Ultra-Fab receiver might be a good alternative as it connects to the underside of the bumper using U-bolts, rather than slipping around it like the E-100 does. Either receiver...
view full answer... - Hitch Bike Rack Recommendations for 4 Inch Bumper on a Travel TrailerIn my opinion the Swagman Platform-Style 2 Bike Carrier for RV Bumpers, # S64663, is the best rack for use on a 4 inch continuously welded steel RV bumper. This rack folds compactly for storage, will also work in a standard 2 inch hitch on a vehicle, and comes with the bolt on receiver for the RV bumper. This style of rack is super easy to load the bikes on and secures the bikes very well, keeping them from contacting each other or the back of the trailer causing damage. If you need to...
view full answer... - Could Ultra Fab Hitch Part # UF35-946402 Fit Bumper Measuring 3 inch by 3 inchSince your bumper is 3 inch by 3 inch the Ultra Fab hitch part # UF35-946402 that you referenced can fit it but you would need to use a 1 inch spacer on the top/bottom and another one on either side so that it fits properly since this is designed for a 4 inch by 4 inch bumper. The spacer would essentially make the bumper 4 inch by 4 inch.
view full answer... - Recommended Bike Rack For Carrying Two 65LB E-Bikes Behind a Truck and Travel TrailerI recommend the Swagman E-Spec Bike Rack # S94FR for carrying your 2 e-bikes. This rack is rated for carrying 2 bikes up to 70lbs per bike and is rated for use behind your 22' travel trailer and pickup with a 2" receiver. The Bolt-On Frame Receiver # C13704 is going to be the best option for adding a receiver to your travel trailer. This will fit a frame from 22"-66" wide and provides a much more secure connection to the trailer than using a Bumper Receiver # UF35-946402
view full answer... - Trailer Hitch Recommendation for a Trailer that has a 84 inch Wide FrameYour trailer has a very wide frame, there are no frame mounted hitches we carry that would work for you due to that width so your best option would be a bumper mounted hitch like the # E-100 designed to fit a 4 inch square continuously welded steel bumper or the part # C19101 designed to fit a 2 inch wide by 4 inch tall bumper. This hitch is for use with RV-approved accessories only. All non-trailer loads - bike racks, cargo carriers and so forth - should be supported with stabilizing...
