On the rear bumper of my travel trailer it has carried 2 non-electric mountain bikes using a Swagman bike rack for 10,000 highway miles with no issues. I shimmed the receiver channel and drilled and safety wired the slop bolts. So far so good and I don't fore see any future issues as I haven't had to mess with it since installation..



by:

It fit the bumper perfectly but my bike rack wouldn't fit without reworking it.



by:

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.

Mark H.

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...

Bob.r

8/28/2015

No problems at all. Used it several times already and works great. I mounted them at the frame extensions.



by:

I’m using this receiver a little differently than it’s intended purpose. After getting some longer bolts and drilling holes in some aluminum angle stock, I mounted it to the tongue of our trailer. Now I have a place to store the head of our weight distribution hitch when it’s not on the truck. I just slide it into this receiver and it’s up, out of the way instead of taking up room in a storage compartment or sitting on the ground. I have a locking hitch pin I can use for added security. A simple and cheap fix.



by:

I ultimately had to return this item outside of the etrailer.com return window, but UltraFab exchanged the product with no problems. Currently using it on my rear bumper with a license plate frame holder.



by:

Fits great on the 4" bumper on our motorhome. Seems very sturdy and should work great for our 2 bike rack, without interfering with the trailer hitch.
I'd probably give it 5 stars, just haven't gotten to use it yet.



by:

Ise this item on my travel trailer to keep my hitch out of the way,off the ground. Love it to store it so I don’t kick it on the ground.



by:

I looked at several options for attaching a bike rack to my camper and this was what I wanted. I looked at several similar items on Another online retailer that had complaints about the receiver falling off because of faulty welds. I am quite certain that this product won’t come apart, in fact, you could probably pick the whole camper up by it. It is built like a tank, and is incredibly easy to install. It was more expensive than the junk on Another online retailer, but I won’t be worrying about my bikes falling off going down the road



by:

It works great I put a bike rack on it and it is fine .



by:

Has held up well on camper to hold bike rack and a carrier.



by:

I placed my order and had my part within a week. Now we can take our bikes with us wherever we go. Just moved the spare tire over and bolted the reciever right on. Thanks guys.



by:

This product was very easy to install and will be perfect for holding our bike rack. Very heavy duty for the price, excellent quality.



by:

Works great for our bike rack.



by:

Exactly what I ordered and on time. E trailer is where I go to get stuff for my camper.



by:

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.

Bruce

8/29/2016

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!



by:

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.

Randy

5/22/2014

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



by:

I got this product our RV rear bumper to put a bike rack forour two bicycles and I'm very happy with the hitch receiver it is well made and great item that I needed to carry our bike.I highly recommend this hitch receiver.

Thank you
Received my bracket on time,
great quality, easy to install, exactly what I was looking for.
Recommend this bracket to any RV person wanting to transport bicycles. Receiver is perfect for my Yakima bike rack...

This product was perfect to attach to my hard shell trailer for our bike rack.
etrailer did a great job from the ordering process to delivery. Thanks for having a great process set-up to buy from you!

Jim O.

Your product has worked out very well, the metal gauge thickness is very strong!



by:

Very happy with the product we purchased for our RV. It fit perfect, and now we can transport our bicycles when we go camping! Now we don't have to take up space inside the RV or the back of the truck!! See attached photos.



by:

They worked great for adding a platform and toolbox onto the back of my travel trailer. I know I couldn't have fabricated and added the hardware for the price!

Rich Z.

2/19/2018

Been a year and lots of miles with bumps and potholes but the brackets have remained tight and working like they should. Thanks



by:

Attached easily to the back of my camper and my bike rack slipped right into the receiver. Overall, a good buy that met my needs.

Frank W.

Great!

This is the 4th item I have purchased from etrailer, as usual a quality product at competitive price, very helpful customer service and on point shipiping, If etrailer has it I will purchase it from them

Teresa M.

Have ordered several items from etrailer and all are quality items that are working the same as the day I received them.

Works just like it should. Just finishing using to go to VA and ride the Creeper trailer. Used just like to carry our bikes to Alaska and back

Don

Still providing good useage. Glad I purchased it.

See what our Experts say about this Ultra-Fab Products RV and Camper Hitch

  • 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 Hitch Recommendation for a 2017 Starcraft Satellite 17RB Travel Trailer
    As long as the 4 inch square bumper on your 2017 Starcraft Satellite 17RB travel trailer is made of steel and welded its entire length then you would need hitch # UF35-946402 because it is the model for 4x4 inch bumpers. I have linked a video of this hitch for you. The combined weight of your carrier and the tote tank isn't very much but you will still want to check the trailer literature to make sure that the bumper is rated for carrying weight and. if so, the amount of weight it can handle.

  • Rear Bumper Hitch Solution for 4 inch Bumper with Limited Clearance Above Bumper
    Due to the limited clearance you have above your rear bumper you'd need to install a bumper hitch that hangs below the rear bumper like the Buyers Products # 3371804060 as the # UF35-946401 needs to install above the rear bumper.

  • Options to Maneuver a Travel Trailer for Set-Up/Parking Without Backing
    We do have a selection of bumper mounted bolt-on hitch receivers such as the Curt RV Bumper 2" Trailer Hitch Receiver # E-100 that fits a 4"x4" bumper and then provides for a 2" receiver; although this is not designed for the type of use you are describing. 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...

  • 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.

  • Trailer Hitch Receiver and Bike Rack for Use on 2007 Jayco Jay Feather 19H Trailer
    The best hitch type for your 2007 Jayco Jay Feather 19H Trailer will depend on its construction, specifically its bumper. I checked the Jayco website for details about its bumper but no information is offered. So, you'll just want to check your owner's manual for information and guidance related to mounting an accessory hitch. If the bumper is a 4-inch square type then you can use a bolt-on hitch like the Ultra-Fab 2-Inch Motor Home Trailer Hitch Receiver for 4 x4-Inch Bumpers, part #...

  • Trailer Hitch Recommendation for Prowler Fifth Wheel
    Best solution we'd have is the Curt Multi Fit hitch part # 13703 which fits frame widths between 22 and 72 inches apart (outside to outside) and fits all frame styles. Only issue is this is a Class III hitch and we don't have any Class IV or V hitches available that are similar. This has a capacity of 3,500 lbs trailer weight. I attached an install video for more info for you to check out as well.

  • Recommended Frame Mounted Trailer Hitch For A 73" Frame Width On A Springdale Summerland 2600
    The only hitch we currently carry that would fit a 73" frame width is the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames Item # UF35-946403. It is a weld on and has a tongue weight capacity of 350lbs. It is not rated for towing. I do not recommend using any bumper-mounted hitch receivers like the Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" BumpersItem # UF35-946401 you linked to unless you know the weight capacity of the bumper.

  • Will the Ultra-Fab 2" Motor Home Trailer Hitch Receiver Work for Motorhome Tire Carrier
    The Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" Bumpers part # UF35-946401 has a 200 lb weight capacity so as long as the weight of the spare tire carrier and spare wheel/tire do not exceed this you will be good. That said, you also need to take the bumper's weight capacity into consideration and abide by the lowest rated component. There isn't any reason you couldn't use this for a motorhome wheel/tire so long as you be mindful of your capacity.

  • 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.

  • Trailer Hitch for 1995 Chevy G20 Van
    There is a hitch receiver that could work for your 1995 Chevy G20 van, so long as your van does NOT have a step bumper. If so, I recommend the Draw-Tite # 75121 hitch, this is a 2" hitch that is a complete bolt-on installation so there will be no drilling required in your Chevy's frame. I have added a link to a video of this hitch being installed on a '94 van for you to check out so you can see the process involved.

  • Can the U-Bolts On the Ultra-Fab Motor Home Trailer Hitch Receiver Be Turned
    The Ultra-Fab 2" Motor Home Trailer Hitch Receiver part # UF35-946401 has a bolt hole spacing of 5" front to back and 4" side to side so it does not sound like it would work for you. However, we do have the Stromberg Carlson 2" Motor Home Hitch Receiver part # BA-100 which has a bolt hole spacing of 5" front to back and 5" side to side so it does sound like it would work for you although I am not quite sure of the intended purpose.

  • 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.

  • Recommendations For Carrying 2 Adult Bikes and 4 Kids Bikes On a Travel Trailer
    I have a better solution for you, the Jack-It 2 Bike Rack for A-Frame Trailers # LC429756 will attach to the front of your travel trailer using the same bolts that hold the tongue jack. This will hold 2 bikes up to 80lbs total on the front of your camper above the propane tanks. If that type of connection will not work for your trailer jack, the Stromberg Carlson Bike Bunk Trailer-Mounted Bike Rack Carrier # CC-275 will bolt to the trailers frame and allow you to use a hitch mounted bike...

  • Recommended 2 Inch Receiver for Zero Turn Lawnmower Fertilizer Spreader
    We don't have anything like the # 13333 that has mounting holes 10 inches apart. For your application you will need to either customize a fit for that part or use a different style like the Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" Bumpers # UF35-946401 which could be bolted to a strong frame crossbeam for your unique need. Another option is to use the Reese Towpower 3-Way ATV Hitch w/ Ball Mount Adapter - 2,000 lbs # RP7065100 for this custom application.

  • Cargo Carrier For Camping Trailer Bumper Mount Capable Of Securing Cargo With Sun/Rain Protection
    It sounds like you are looking for a enclosed carrier like the GearDeck 17 # H00604 as we do not have a cover for the 24x40 etrailer Cargo Carrier # e99050. The GearDeck carrier will allow you to protect your generator and other gear from the rain and sun. You are able to Lock # 131D the lid for the carrier as well to add security to your gear. You will need a Ultra-Fab 2" Motor Home Trailer Hitch Receiver for 4" x 4" Bumpers # UF35-946401 to slide the carrier into as it is designed to...

  • Clamp On Fifth Wheel Bike Rack Options for eBikes
    I am happy to help you find the right bike rack set up for your fifth wheel trailer. Unfortunately, the Hollywood RV Rider # HLY64FR requires a receiver with at least a 350 lbs. TW capacity. It is not compatible with Bumper Mounted Hitch Receiver Adapters (see photo below), but it is specifically designed to support heavier bikes such as your 2 ebikes.

    The Curt # E-3S hitch you mentioned is recommended for use on a truck step bumper, as shown in the provided diagram. A bolt-on hitch like the Ultra-Fab # UF35-946401 would be a better choice. This hitch is designed to fit bumpers that are up to 4-1/2 by 4 inches. The bolt on receiver has a 200 lb capacity, but you'll need to check with the RV manufacturer to determine the capacity of the bumper. You'll need to abide by whichever capacity is lowest.

  • 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, anything...

  • Solutions for Towing Forest River Roo Travel Trailer and Carrying Bikes Simultaneously
    There are a few different options that might work for you. A towing bike rack can be a good option depending on the tongue weight of your camper. The Curt # C18013 used in conjunction with an extra long ball mount like # 2736 or # D-28 (choose the one with the rise or drop you're needing) might be a good option, but keep in mind that the tongue weight capacity of the hitch would be reduced by the weight of the rack and the bikes. For instance, say the three bikes weigh 100 lbs. The rack...

  • 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...

  • Alternate Mounting of Ultra-Fab 2" Motor Home Trailer Hitch Receiver
    I contacted the Tech Rep at Ultra Fab Products, they stated that it can be mounted underneath but they do recommend it on top. The Ultra-Fab 2" Motor Home Trailer Hitch Receiver, # UF35-946401 is designed, tested and weight rated for an installation of weight setting above the bumper not below. Any alternate installation of product is determined by the purchaser with that understanding. They added that if you are going to be installing a bike rack on the hitch, be sure to pay very close...

  • Installation of a Ultra-Fab 2-Inch RV Trailer Hitch Receiver Part UF35-946401 on a 4-Inch Bumper
    You are correct. The Ultra-Fab 2-inch motor home trailer hitch receiver # UF35-946401 is designed to bolt around a 4-inch RV bumper and the receiver opening will be on the topside of the bumper. This receiver is designed for mounting accessories like a bike rack, and not for towing purposes. It has a 200 pound capacity. Make sure you do not exceed the weight rating of your RV bumper. So if the bumper has a lower weight rating, you will want to go by the lower weight rating.
