Video Transcript for Ultra-Fab Products Specialty Trailer Hitches UF35-946401 Review

Today we're going to review part number UF35-946401. This is the Ultra-Fab, 2 inch Motor Home Trailer Hitch Receiver for 4 inch square bumpers. You can bolt this receiver to the underside of your RV's bumper, to help create a 2 inch by 2 inch trailer hitch receiver opening. With that receiver opening at the Rear View Motor Home, you can use hitch mounted accessories in the Hitch Receiver, like bike racks, cargo carriers. You do not want to use this for any towing. The other thing is you want to do make sure when you do use hitch mounted accessories like a bike rack or cargo carrier, you do want to make sure those accessories are RV approved because certain ones will be RV approved to be able to take the vibration at the back of the motor home.

So, you do want to make sure the bike rack or the cargo carrier is RV approved. Now this does bolt around the RV bumper, you can see it uses the zinc plated hardware the U-bolts, the nuts and the washers are all in included. This will bolt around a 4 inch RV bumper. The hitch itself is made of a nice sturdy steel construction, has a nice black powder coat finish. The receiver opening again is 2 inches by 2 inches, now the weight capacity would be 200 pounds, but the one thing you do want to make sure is the bumper that you bolt this too, you do not want to exceed the weight rating of your bumper. So if the bumper has a lower weight rating, you will want to go by the lower weight rating.

That should do it for the review on part number UF35-946401, the Ultra-Fab 2 inch Motor Home Trailer Hitch Receiver for 4 inch square bumpers. .

I received this product and immediatley installed on my camper bumper, while installing I found two of the 4 lock nut would not screw on to the "U" bolts provided. I then found two of the same size nuts in my toolbox and completed the install. After inserting the bike carrier one of the "U" bolts broke off, It looks as if the "U" bolts are made of a cheap material.I had to purchase a "U" bolt from the local hardware store to replace the broken one. I don't know if I would recommend this to anyonebecause of the faulty "U" bolt. 81601


Comments

After replacing the cheap U bolts with new ones, so far the product is work well.

This was the product I needed to store an accessory from my truck on my fifth wheel camper bumper while not in use. I actually mounted this "vertical" to store my motorcycle carrier "out of the way". I could see mounting this normally to carry light weight accessories while trailering my fifth wheel. 222943


Comments

After a year, product is still what I wanted and doing what I needed. Actually moved to a new fifth wheel in December and brought this forward to the new camper. Very handy!

I ordered and received two of these hitch receivers and installed them on the rear bumper of my camper to carry my 150 cc scooter. Shipping was great and parts mounted without any problem. All hardware was included and fits perfect. Have purchased other items from etrailer previously and look forward to additional items in the future. This company is great to deal with. 154331


Comments

Did you end up having any problem with the weight of the scooter breaking the bolts..? I am buying 2 to do something similar...making a carrier for my generator and plan on using 2 hitches...

Hi, I was driving back home after our vacation and utilizing the bike rack, along with the hitch receiver, and adapter bars. 1/2 way through Nebraska, a Mustang pulled up while i was driving and yelled, "do you have a bike rack?" I said yes, and he yelled it had fallen off! This was on interstate 80 going 70 mph. I pulled over, and the rack was gone. So we drove to the next exit and back tracked. I was just hoping nobody was hurt. About 7 miles back, we saw the bikes on the side of the road still attached to the rack. We went to the next exit, turned around, came back and gathered the bikes and real with the help of a state trooper. After looking at the rack, i could see it was still attached to the receiver i purchased, but the u bolts had snapped. 4 damaged bikes due to defective u bolts. ••• 273631

Haven't used it yet but appears to be well constructed of heavy duty quality materials. Installation was simple with a standard 3/4" wrench, but a deep socket would be handy. 126364

I have been carrying my bike on the back of my travel trailer for about 4000 miles now and have not had a problem. Cant ask for anything more.

etrailer shipped extra fast and communicated well and I will buy from them again but stay away from this product.The bolts and nuts are very poor. All four threads needed to be filed and chased with a die to accept a nut. You could see when it came out of the box there was no way a nut would ever go on the bolts without work. 2 of the 4 lock nuts had burrs on them and were unuseable. I threw away all 4 nuts and bought new and I am considering replacing the bolts before installing the hitch and hanging expensive bikes on it. This hitch may be inexpensive but in this case you get less than what you pay for. 99361

This hitch receiver arrived on time. It is made of heavy duty steel, and looks to be a quality made piece. It worked perfectly for my need on the rear bumper of our travel trailer... I do want to also mention that in reading reviews before purchasing this receiver, some other people mentioned getting the wrong nuts with the hardware. Well, these people apparently have no mechanical ability, or do not know what nylock ( self locking ) nuts are.. This item was perfect just as advertised.. 138501



- UF35-946401

by: Jeremy K.06/12/2016


This is a great product. I was hesitant to purchase because older reviews noted poor threads on the bolts. They were older reviews so I decided to go for it since the cost is nearly half of other bumper receivers. I received the product in perfect shape. The nuts threaded on without issue. I attached a hitch basket and put about 100lbs of stuff on it and drove 800 miles with it on the back of my travel trailer. This is a great product asst a great price. 260477

I am extremely pleased with the quality of the construction and ease of installation(six minutes) of my new RV bumper receiver to be used for our four-place bike rack. I have been casually looking for a product like this for the past two years and by chance came upon the etrailer site. No longer will I have the burden of loading/securing and/or unloading bikes from the bed of our pick-up truck each time we set up or take down our camp site 227044

This receiver is exactly what I was looking for to add a grate to the bumper of my travel trailer. Easy installation, solid receiver. I come back to Etrailer time and time again because their products are always superior, good pricing, excellent support staff if I have questions. When you order an item Friday night and it arrives Monday, that defines excellent service.... Be back for sure. 307997

Both of the items I ordered came today. The quality looks to be excellent. I ordered these two things to create a hitch on a tractor I recently purchased.

This is my second order for this part. The first one was ordered in 2012 and was mounted to a flatbed trailer so I could attach a receiver mounted wench. This one is for mounting on my RV for a bike carrier. Price is good, quality is good. Wouldn't buy a second one if I didn't think it was worth the money. 151834

I received this back ordered trailer hitch receiver earlier than expected. Installed it the first night. I moved the spare tire to one side and installed the receiver in the center.

I was very impressed by how quickly I received my order. The parts were all there, and the overall quality looked good. However, the threading on the U-Bolts does not seem to match the nuts that were provided. I will have to go to a hardware store to see if I can find a better match. 82569

by: Don04/17/2013


I liked the looks of the received product, just as advertised. The bolt ends, tho, were very rough and unfinished, and would not accept the nuts. I cleaned the threads with a file but nuts still wouldnt start or got immediately too tight to cinch up. I ended up changing out the nuts. 76634

Seems like a good product. Have not officially used it. When I mounted it to the bumper, I attached my cargo carrier and got on the carrier and started to jump up and down on it. Everything held up well. I weigh 149 pounds. I plan to carry my black and grey water tanks on the carrier. 85362

Do you have a question about this RV Hitch?


  • Recommended Cargo Carrier and Hitch for Rear of Travel Trailer
  • We do not offer a bolt-on cargo carrier, but you could certainly use a hitch mounted carrier. The first step would be to install a hitch like the Curt # E-100. The hitch is compatible with 4 inch square bumpers, and offers a 350 lb tongue weight capacity, which means that the weight of the carrier used plus the weight of the gear carried upon it could weigh no more than 350 lbs. Because of the extended distance between the rear axle and the back bumper of the average travel trailer,...

This hitch is designed to fit bumpers that are up to 4-1/2 by 4-1/2 inches.

This receiver is designed for mounting accessories like a bike rack, and not for towing purposes. It has a 200 lb capacity.

We offer two types of trailer hitch for use on the back of an RV such as your 5th wheel, a bumper-mount type like the Ultra-Fab 2-Inch Motor Home Trailer Hitch # UF35-946401 (see linked video) as well as a frame-mount multi-fit receiver such as # UF35-946403, both rated for use with accessories, not towing. All options can be seen on the...

  • Recommended Hitch and Hitch Bike Rack for 2014 Rockwood Ultralite 5th Wheel
  • You need to use an RV-rated hitch bike rack in the hitch you will install on the rear of your 5th wheel trailer. Regular bike racks meant for use on cars, like the excellent Kuat NV 2.0 # NV22G, cannot be used on a trailer. This is due to the extra stresses placed on carriers that are mounted on the rear of a trailer. Let's start with a hitch for your trailer. We offer both bumper-mount and frame-mount 2-inch hitch receivers for trailers that can be seen on the linked page. Your best...

  • Trailer Hitch Recommendation for a 2005 Savoy SL Travel Trailer
  • What I recommend for a bumper mount hitch is to go with # UF35-946401 which fits 4 x 4-1/2 inch bumpers. However, use a bumper mount hitch only if it is a square continuous welded steel bumper. If the bumper is not square, not continuously welded, and/or not steel, I recommend using a frame mount hitch. The most popular frame mount hitch that fits the widest variety of frames is # 13703. It fits box frames, C-channel frames, and I-beam frames. It can be welded on or bolted on....

  • Ultra-Fab RV Bumper Hitch Recommendation For Motor Home
  • While we do have a hitch that will work for your needs, the Ultra-Fab Bumper Mount Hitch # UF35-946402 you referenced is designed specifically for a 4 inch by 4 inch bumper and would not fit. The Ultra-Fab Bumper # UF35-946401 is a perfect fit as it is intended for 4 inch by 4-1/2 inch RV bumpers with a weight capacity of 200 lbs. It features a 2-inch receiver opening with a plate measuring 5-7/8 inches by 4-7/8 inches. Just a reminder, this is intended for RV-approved accessories...

  • Frame Mounted Trailer Hitch for Travel Trailer
  • We do indeed offer some hitches that are designed to bolt to the frame of your travel trailer. If the frame members on your travel trailer are between 18-51 inches apart, the Curt Hitch # C13701 would be an excellent choice, with it's tongue weight capacity of 500 lbs. For frame members between 22-72 inches apart, use the Curt Hitch # 13703, which has a tongue weight capacity of 350 lbs.

  • Mounting Ultra Fab # UF35-946401 Under Bumper
  • It is acceptable to mount the Ultra Fab # UF35-946401 underneath the bumper. Make sure the 200 lb capacity of the receiver or the capacity of the bumper (whichever is lower) is not exceeded. This receiver is meant to mount to a 4 inch Steel RV bumpers, and not to a car or truck. It is not intended to be used for towing purposes.

  • Bumper-Mounted Bike Rack Recommendation for 2016 Coleman Travel Trailer with 4 Inch Bumper
  • 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 Mighty Rack, 2 Bike Rack # S80500. 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 the rack. This bike rack will install around...

  • Receiver Size of Ultra-Fab 2-Inch Bumper Mount Hitch # UF35-946401
  • The Ultra-Fab 2-Inch Bumper Mount Hitch, part # UF35-946401, is only available with a 2-inch receiver opening. All of the RV bumper mount hitches will have a 2-inch size receiver opening. Trailer hitch receiver sizes are available in three different sizes, 1-1/4 inch, 2-inch, and 2-1/2 inch. The two most common sizes would be the Class I and Class II 1-1/4 inch, and the Class III and Class IV 2-inch. The Class V 2-1/2 inch size is used on heavy-duty trucks. I am including a link...

  • Hitch Receiver Size of Ultra-Fab 2-Inch Bumper Mount Hitch # UF35-946401
  • The Ultra-Fab 2-Inch Bumper Mount Hitch, part # UF35-946401, is only available with a 2-inch receiver opening. All of the RV bumper mount hitches we carry have a 2-inch size receiver opening. We have the Brophy Hitch Reducer, part # HT02, that will reduce a 2-inch hitch to a 1-1/4 inch size, because it is a sleeve design it will not reduce the tongue weight capacity. Since you did not mention what you will be doing with the bumper mount hitch, I cannot for sure recommend the # HT02...

  • Recommended Trailer Hitches For 2002 Winnebago Minnie Motor Home
  • The Trailer Hitches we offer for RVs depend on the installation of the hitch. Some are able to handle a bumper mount hitch and others are either bolted or welded to the RV frame. If you are looking for a frame mount hitch and your frame width is between 18 and 51 inches I recommend part # C13702. This is a Class lll hitch and it has a 2 inch receiver opening. For a bumper mount hitch and if you have a bumper that measures 4 x 4-1/2 inches I recommend part # UF35-946401. This hitch...

  • Installing Ultra-Fab # UF35-946401 Bumper Mounted Receiver on 2 x 2 Pipe Bumper on RV
  • When you describe a 'pipe bumper' do you mean that its round, or is constructed of square tube? If it's a round pipe, I wouldn't recommend attaching a receiver to the bumper as any tongue weight (downward force applied to the receiver) would rotate the receiver tube downward. If you're talking square tube, the Ultra-Fab # UF35-946401 wouldn't be your best option as the threaded portion is about 1-3/4 of an inch long. It wouldn't cinch tight enough, plus the spacing between the legs...

  • RV Bumper Hitch Recommendation that Can Mount Below Bumper
  • I have a solution for you, but the RV Bumper 2" Trailer Hitch Receiver # S64025 that you referenced can only be used with the hitch opening on top of the bumper. Instead you would want the Ultra-Fab 2" Motor Home Trailer Hitch # UF35-946401. This hitch can be used with the opening on the bottom of the bumper. Be sure not to exceed the weight capacity of your bumper, check the owners manual of your vehicle for more info on that.

  • Why Cant the Bumper Mounted Hitch Recevier UF35-946401 Be Installed on Decorative Bumper Cover
  • The Ultra-Fab 2 Inch Motor Home Trailer Hitch Receiver # UF35-946401 is not designed for use on decorative aluminum bumper covers because the installation of the receiver and the weight of the accessory used in the receiver would likely damage the decorative aluminum cover. When the bumper cover becomes damaged, the receiver would no longer be installed securely enough on the bumper and could move while a hitch accessory is being used.

  • Is there a Bumper Mount Hitch that Will Fit a 4-3/8 Inch Bumper on an Arctic Fox Trailer
  • Bumper mount hitch # UF35-946402 is designed specifically for 4 inch square bumpers so I cannot recommend it on a 4-3/8 inch wide bumper. Hitch # UF35-946401 would be a better fit since it fits 4-1/2 x 4 inch bumpers. All of the other options are either going to be 4 x 2 or 4 x 4. Also check with the trailer manufacturer to make sure the bumper is rated for use with a hitch.

  • Is Trailer Hitch capacity Reduced When Using Curt Multipurpose Ball Mount # D210
  • The Curt Multipurpose Ball Mount, part # D210 will not reduce the weight capacity of your trailer hitch. The # D210 does have a 7,500-lb towing capacity and a 750-lb tongue weight capacity so you will need to make sure you do not exceed those capacities when using this ball mount.

  • Trailer Hitch Availability for Gulfstream Sea Hawk 5th Wheel Trailer
  • We offer both bumper-mount and frame-mount hitch receivers for use on 5th wheel trailers that can be seen by clicking on the linked page. All have a 2-inch receiver opening. Some of these are bolt-on products while others require welding. For example, part # UF35-946401 from Ultra-Fab is a bolt-on bumper mount hitch, while part # UF35-946403 is a weld-on frame-mount hitch. I checked the Gulfstream website for bumper/frame specs for your 5th wheel but these are not provided, so you'll...

  • Trailer Hitch for a 2017 Rockwood Roo to Carry Bikes
  • Since Curt trailer hitch # C13702 is a universal type of product you have to look at the installation instructions and compare them to your trailer to determine fit. I have linked the installation instructions for you. If the bumper on your trailer is 4-1/2 x 4 inches then you can use # UF35-946401 but with these you have to be careful not to exceed the capacity of the bumper (if it is rated for weight carrying). Another option is the bike bunk # CC-275 which mounts to the front...

  • Curt 13703 Hitch Dimensions from Frame Bracket to Hitch Opening
  • I attached two pictures that detail where the hitch tube and opening are in relation to the bracket for you to check out. Hitch manufacturers basically refuse to get into the specifics of the hitch extender capacity reduction for fear of people assuming they can carry more than they should based on hypothetical math problems. Hitch extenders though are even more hard on hitches when installed at the back of an RV because trailers have much rougher ride qualities than vehicles. I really...

  • Will Ultra-Fab Motor Home Trailer Hitch # UF35-946401 Fit a 2008 Chrysler Aspen
  • The Ultra-Fab Motor Home 2-Inch Trailer Hitch, part # UF35-946401, is intended for installation on the rear of motor homes that have an exposed 4-inch bumper. Installation requires that the bumper be fully open in order to allow the U-bolts to attach securely. This hitch is not suitable for use on your 2008 Chrysler Aspen. The bumper on your vehicle is designed to protect the passengers in the event of an impact. Even if you removed part of the bumper cover to expose the bumper itself,...

  • Hitch and Bike Rack Recommendation for a 1999 Jeep Wrangler
  • If you had a 4 inch by 4 inch square bumper the # UF35-946401 would fit your 1999 Jeep Wrangler, but this isn't the best setup we have available. A much better setup would be a frame mounted hitch custom fit for your vehicle. For that I would recommend the Hidden Hitch part # 87431. Most likely the bumper of your Wrangler isn't rated for towing or carrying a bike rack so this would be a much better option. For a bike rack I would recommend the Thule T2 2-Bike Rack # TH9044.

  • Dual Hitch Recommendation for Flat Towing Car and Carrying Bike Rack at the Same Time
  • Sounds like you want to install the Ultra Fab Hitch part # UF35-946401 vertically so that the opening faces up instead of behind the RV. I can't safely recommend you do that since the hitch hasn't been tested in the orientation. A better option would be something like the # RM-077-4 that has a 4 inch rise built into it so that you can install the rack in the upper opening and use your tow bar in the lower one.
