Video Transcript for Review of Ultra-Fab Products RV and Camper Hitch - RV Bumper Mount Hitch - UF35-946402

Hello everybody, this is Jeff at 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.

Average Customer Rating:  4.7 out of 5 stars   (220 Customer Reviews)

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.


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

This product has preformed as it should, no issues and I can be confident that it will withstand its purpose, thanks again


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,


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.


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.


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 bounce at all with hitch


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.


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.


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.


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.


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.


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.


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.


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 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.


the item looked and worked as advertised


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.


Well constructed, very easy to install, negates fabricating or adapting a hitch by taking advantage of existing 4" bumper.


E trailer is a consistent place I shop for fast delivery, great communication and products as described.


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.


Just right to tow my little aluminum boat behind the camper !


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).

Etrailer Expert

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..

Rich A.


It has worked great, but now I have changed my Trailer and do not need it anymore


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!

Etrailer Expert

Rachael H.


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.


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.

Dave P.


A year later, I couldn’t imagine not having the bikes and the grill on the back of the RV. Great product


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.

Robert G.


The attachment is working great. I need to store it outside and see no physical deterioration.


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.

This trailer hitch is designed to fit your RV bumper measuring at 4 inches by 4 inches. I have sent your information over to our customer service department for them to get in touch with you.

  • Trailer Hitch to Carry a Bike Rack on Back of Trailer
    No; the only way to carry your bike rack is to mount it to your trailer's frame. The Curt Adjustable Width Trailer Hitch Receiver # 13703 will fit box frames, C-channel frames, or I-beam frames that are between 22" and 72" wide, so if your boat trailer has that this hitch can work for you. Also please keep in mind that your bike rack does need to be rated for use behind a trailer. For this I recommend checking out the Swagman Trailhead # S63381 has a 35 lb per bike weight capacity and...

  • Kuat Transfer V2 2" Bike Rack Mounts For Travel Trailer and 2-1/2" Reducer Sleeve
    Yes, the Kuat Hitch Receiver Reducer Sleeve # KU93VR will work with the Kuat Transfer V2 Bike Rack # KU84FR in your 2-1/2" receiver. The reducer is held in place inside the receiver with magnets allowing you to install the bike rack like it is in a 2" receiver. Since the Kuat Transfer is safe to use on travel trailers you can mount it on your Flagstone 832bws. We do have the Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" Bumpers # UF35-946402 if you do not already have a receiver...

    We 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...

  • Trailer Hitch Fits for 2016 Forest River Crusader 28RL 5th Wheel Trailer
    All of the hitches we offer for use on the rear of a motor home, 5th wheel or other RV are the 2-inch size. A Class II hitch has a 1-1/4-inch receiver opening. No hitches of this size are offered for use on trailers due to the high mechanical stresses that can be found at the rear of an RV. I checked the specs for your 2016 Forest River 28RL but I could not confirm the frame dimensions or rear bumper construction. If you have a continuously-welded 4-inch steel bumper you can use Ultra-Fab...

  • Availability of Bumper Hitch that Can Fit 4 inch Square Bumper for Carrying Generator
    Only the RV manufacturer will be able to tell you if the bumper is strong enough for the weight of a carrier and generator, but we have the Ultra Fab bumper hitch part # UF35-946402 which is designed for 4 inch square bumpers and has a 350 lb tongue weight rating. Assuming your bumper is rated for the weight this would fit and work well.

    The Ultra-Fab 2" Motor Home Trailer Hitch Receiver part # UF35-946402 will fit RV's with a 4" wide x 4" tall steel bumper and bike racks with a 2" receiver tube. However, in order to use a bike rack on the rear of an RV the bike rack must be RV approved. I do have an RV approved bike rack option for you but the Thule T2 Classic 2 Bike Platform Rack part # TH69TX is not.

    The 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...

This rack has a fold down mast, but the rest of the frame is rigid to give the support needed for RV use. The Swagman Platform-Style 2 Bike Rack for 2" Hitches for RV Bumpers # S64663. is a bike...

  • Recommended Motorcycle/Scooter Carrier With Hitch Receiver For Motorhome
    You 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.

  • Can an Enclosed Trailer be Towed Behind a 5th Wheel Trailer
    Towing one trailer behind another trailer is illegal in many places so the first thing you are going to want to do is check the laws where you will be traveling. It is also just not a good idea because it is not safe. The likelihood of jackknifing and a bad sway condition is greatly increased plus there is a lot more momentum pushing you forward. If installing a trailer hitch on the 5th wheel I strongly recommend a frame mounted hitch, not a bumper mount hitch. The bumper mount hitches...

  • Trailer Hitch Recommendation for Carrying a Bike Rack on a Trailer
    The 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.

A lot of times fith wheel trailers are so wide you can fit a bike rack to the side of the spare and not have the bikes hanging over the rear of the trailer.

  • Recommended Bike Rack for Trailer with Tilting Bumper Mounted Spare Tire
    For your camping trailer that has a tilting bumper mounted spare tire, I recommend looking at an RV approved hitch-mounted bike rack like the Swagman Dispatch 2 Bike Platform Rack # S44FR. This will slide into a 2 inch trailer hitch receiver and hold 2 bikes of up to 45 pounds each. When the bikes are unloaded from the carrier, the upright mast can be folded down to allow you to tilt back the spare tire on your trailer for rear storage access. This carrier also includes a hitch and cable...

  • RV-Rated Bike Rack Recommendations for Class A Motorhome
    A 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...

    Two of the Ultra-Fab 2" Motor Home Trailer Hitch Receivers # UF35-946402 would in theory hold 650 lbs, but I believe there would be a weight capacity issue on the bumper of your Safari. I can't imagine it's rated for holding 650 lbs so you'd want to first confirm with them that you'd have the needed bumper capacity.

    This trailer hitch has a 350 pound tongue weight rating, so you will want to make sure that the weight of your Moped, and the carrier are under this combined weight rating. For hauling your Moped you will want to make sure that you are using an RV approved carrier. Due to the extended length from the rear axle to the receiver, the forces exerted on the carrier and cargo will be exaggerated. That is why this hitch is intended to be used in conjunction with RV-approved accessories only....

    Since 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.

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.
