Video Transcript for Ultra-Fab Products RV and Camper Hitch - Frame Mount Hitch - UF35-946403 Review

Speaker 1: Today we're taking a look at the Ultra Fab 2" Trailer Hitch Receiver for trailer frames. This unit provides a 2" by 2" trailer hitch receiver opening at the rear of your trailer or RV. This is perfect for mounting the bike rack, cargo carrier or other hitch accessory. Please keep in mind that this is not to be used for towing applications.It welds onto I-beam, C-channel or rectangular trailer frames. Also keep in mind that a gusset may be required to weld onto I-beam frames. And a plate may be required to weld onto a C-channel frame.

Its constructed of heavy-duty, powder coated steel. Does a great job at resisting rust and corrosion. Features a 3500-lb weight load capacity and a 350-lb maximum tongue weight capacity. You always wanna be careful not to exceed the RV frame rating provided by the manufacturer. And one of the neat features about this unit is that it's adjustable.So it has these arms right here that can slide out.

It's able to adjust anywhere from 47-1/8" all the way out to 77". And it is a weld on installation. So these arms extend out. Really nice design. Same construction and same finishing as the main hitch.

And then it comes with some hardware here, and those are set bolts. So on the back side, once you have the arms extended where they need to be, you thread in the bolt here to kinda lock that arm into position. And again, it's a weld on installation designed to be welded onto the RV or trailer frame.Again, adjustable from 47-1/8" to 77". Right here you have a 2" by 2" opening. This will accept a standard 5/8" diameter hitch pin or hitch lock.

And then you have safety chain loops right here that provide a suitable point for securing any accessory that you might have if it has an accessory strap or a tie down strap or a cable or chain. That's what these are used for. Overall really nice design. And that's gonna do it for today's look at the Ultra Fab 2" Trailer Hitch Receiver for trailer frames.

Excellent product! The item was out of stock but communication with ET was on great. They notified me of when the unit would be available and when it was shipped and delivered as well. It was in good condition other than being a bit scuffed up by the shipping company. It fit my 31' 5R just fine and the welder took only an hour to install it. Very sturdy product! It'll work perfectly for my bikes and would likely work just fine for a Moped as well. One word of caution; you will likely have to purchase an extension (mine is 8") for the receiver if you have a fiberglass body. It makes the bikes wobble a lot more so you'll have to use tie-down straps (a good idea anyway). Very happy with this. 219967

As always Etrailer has come thru. I ordered this part from another vendor cancelled it because of delay and ordered from Etrailer and received it a day early. Thanks Lori PS. Now my bike rack, my trucks 5th wheel hitch and my rv receiver hitch is thanks to Etrailer and my credit card. Etrailer is the most professional organization I have ever done business with. 558894

I put this hitch on the back of a Jayco Pinnacle 5th wheel to utilize a Bike carrier, it worked great, the ability and range that it adjusts fit the need perfectly. This is a Weld on application that is made very solid. 563976

Excellent product. Very tough, straight and true. Had it welded up onto my 5th wheel by a trailer welding shop for about $110. I use it for a bike rack only but an equipment rack would work also. 447224

I purchased this hitch receiver so that I could attach a bike rack to the back of my camper. It was easy to assemble, adjust and install with the help of a friend who is a welder. It does add weight to the back of the trailer and load needs to be adjusted to reduce trailer sway in my case. 571408

This is my 2nd Ultra-Fab Trailer Hitch I have ordered and installed from etrailer. There is a reason for that, it is a great product! I have never been disappointed from any etrailer product. The service is next to none at etrailer! The Ultra-Fab Hitch is very well made, with quality craftsmanship. I would not hesitate to order again. (If I have to! Dang Hail Storms in Wyoming!) 383468

I dont know how to weld, so I had my shop at work do it for me. Our welder had it done like like 40 minutes! The build quality on this hitch receiver is top notch. It is very heavy, sturdy and well built. I have complete faith in the hitch itself. I plan to use a Lets Go Aero BikeWing T4 bike rack and one of my bikes is a $5000 bike, so I needed to make sure whatever I got would be sturdy and well built. 551056

  • Recommended Hitch Receiver For Jayco Travel Trailer And 4-Bike Rack Application
  • For your 2017 Jayco Jay Flight SLX 267BHSW travel trailer, I recommend the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames # UF35-946403. This is a very nice weld on option adjustable from 47-1/8 to 77 inches. For a bolt on option, I recommend the Curt Adjustable Width Trailer Hitch Receiver for RVs, 22" to 72" Wide # 13703. The Curt model recommends the use of stabilization strap # 18050. The weld on options are nice because they don't require any drilling into your frame, but...

  • It is absolutely possible to install a trailer hitch on your 2006 K-Z Escalade trailer; it will only require that your trailer have a box frame, C-channel frame, or I-beam frame that is between 22 inches and 72 inches wide. Should your trailer have that you will be able to use the Adjustable Width Trailer Hitch Receiver for RVs # 13703 which will can either bolt or weld onto your trailer's frame.

The Curt Adjustable Width Trailer Hitch Receiver for RVs, # 13703, is a universal, adjustable hitch which will work on frames with a width of 22 inches up to 72 inches.

  • Trailer Hitch and Cargo Carrier to Hold a Generator on an Airstream Trailer
  • Ultra-Fab 2" Trailer Hitch # UF35-946403 is pretty much a universal fit type of item. If the frame spacing on your Airstream is 47 to 77 inches then this hitch can be installed. It has a 350 pound tongue weight capacity so the combined weight of the cargo carrier and the Honda generator cannot exceed that limit. For a cargo carrier than can be used on the back of a trailer or RV I recommend TorkLift carrier # TLA7752 because it is large enough to hold the Honda 3000 generators. The...

  • Recommended Trailer Hitch For 2016 KZ Sportsman Travel Trailer
  • The trailer hitch receiver I recommend is the Ultra-Fab # UF35-946403. This trailer hitch welds onto the trailer frame. This hitch will work with I-beam, C-channel or rectangular trailer frames and adjusts to work with frames from 47-1/8 to 77 inches. You can compare the mounting bracket of the # UF35-946403 hitch to the Curt hitch # 13703. The Ultra-Fab hitch will sit about 3 inches higher than the Ultra-Fab hitch does. I have attached a photo of both hitches you can compare.

This hitch can be bolted or welded to your frame and is compatible with box frame, c-channel frame, or I-beam frames.

  • Hitch, Bike and Motorcycle Carrier for a 2017 Rockwood Roo 233S Hybrid Trailer
  • I have a solution for you, however the Kuat Transfer, part # TS02G, isn't approved for use on the rear of a trailer or RV. This is because of the distance between the axle and the location of the hitch causes additional stress to be put on the bike rack and the hitch, potentially damaging less sturdy racks. I recommend for your eventual goal to first verify the weight capacity of your bumper in your owner's manual or with your manufacturer to make sure that loading the motorcycle won't...

We have Ultra-Fab hitch # UF35-946403 that fits frame widths of 47 to 77 inches or Curt hitch # 13703 that fits frame widths of 22 to 72 inches. I have included links to the installation instructions for both and a video showing an example installation of the Curt hitch.

These both are bolt on options. There is also a weld on option in the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames # UF35-946403. My recommendation is the Curt # C13704 based on the ease of installation with the bolt-on method from the bottom...

  • Welding Ultra-Fab Hitch to I-Beam Frame and Length of Receiver
  • The Ultra-Fab Hitch # UF35-946403 weighs 50 lbs; I went to the warehouse to measure how far the receiver extends away from the tube and found it to be approximately 5-3/4". As for how the Ultra-Fab welds onto an I-beam frame I contacted the manufacturer and was told that in order to do this, gusset plates would need to be fabricated and used by the installer. Should you also be in need of a bike rack, I have added a link to the racks we carry which are approved for use with an RV.

The Ultra-Fab may work for you but there is another option I also recommend checking out, the Curt # 13703.

  • We offer hitch receivers for use on RVs that you can see on the linked page. Both bumper-mount and frame-mount type hitches are made and it will be a good idea to check with your trailer's manufacturer to confirm which type is best for your particular RV. Examples of both types are parts # C19101 which fits 4 x 2-inch bumpers (as long as they are NOT a C-channel type) and # UF35-946403 which fits trailer frames between 47-1/8- and 77-inches wide (measured outside edge to outside edge).

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 the MaxxTow MaxxHaul Aluminum Motorcycle Carrier for 2" Hitches - 400 lbs # MT70101 for your scooter. I recommend the Motorcycle Soft Loops # 06303...

Instead check out the Curt Hitch part # 13703. As long as your trailer frame is between 22 and 72 inches this hitch should work well for you. I attached an install video for you to check out. You should note that this is a general application product, and it is the responsibility of the installer to select a structurally safe location...
