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.

Use this receiver to carry a bike rack or cargo carrier on the back of your trailer. Do not use for towing. Unit welds onto I-beam, C-channel or rectangular fifth-wheel trailer frames.by: Steven 10/05/2023
Had it installed on back of fifth wheel and it has held up very good carrying 2 70 lb electric bikes.
Much better than the bike rack attached to it has not handled the load as well. W
I would recommend tHis hitch!
by: Marsha Z04/30/2020
We needed to add a bike rack to our Cougar 28sgs fifth wheel and felt the fifth wheel bumper would not be strong enough to support carrying bikes. We purchased this hitch and turned it upside down so it rested on top of the fifth wheel bumper and welded it to the frame of the fifth wheel for support. The hitch was a perfect width to reach the frame of the fifth wheel.
by: Joel 05/04/2023
Great experience!! The ad was clear with helpful pics and was accurate. The order shipped in one day and delivered within three working days. It is more heavy duty than I anticipated which is great. Workmanship looks excellent. I will have to hire a welder to attach it but it should be simple and work well. Exactly what I needed to be able to transport my ebikes on the back of my travel trailer when I go camping. I will keep this company on my recommendation list.
by: James10/04/2018
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.
by: Jason07/13/2022
Prompt delivery. Product is much more heavily made than expecting considering it’s not recommended for towing. Quality material and construction. I plan to mount it upside down to keep adequate ground clearance on the back end of my pop up camper.
by: Sean08/08/2018
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.
by: Ray04/27/2019
Installed this hitch along with a heavey 1/4" x 4'' steel rear costom bumper and attached them both to the frame and welded both together to make it even stronger to pull just about anything. Another trailer or a car dolly or cargo hauler.
by: Michael 04/30/2023
Very heavy duty hitch. Easy to fit in between the frame of the Rv with the adjustable arms.
by: James04/03/2023
I can't rate this yet because the middle section was missing. Box had large holes torn and UPS tried to cover them with cardboard box and tape. Melissa gets 100 stars for helping me. Hopefully all the parts will make it here.
by: Dana 09/11/2022
This is an excellent product. It was much stronger and better made than I anticipated. I had a certified welder come to my house and weld this hitch to my E-Pro trailer. I can now mount my bicycle rack to carry my two e-bikes safely while travelling. Recommended product.
by: Matthew 04/12/2021
Packaging had me very worried, because it was taped and repaired like it been through a war on both inside and outside boxes. I would have given 5 stars otherwise. Seems like a good quality hitch and fit my application. Thank you for finding a nice product for me!

Still going strong after a year! Great hitch
by: Jon01/04/2021
Purchased the product and had it shipped to a courier pickup location. Packaging was a little beat up but no damage. Had the product installed on a 2018 36 ft fifth wheel. The product needs to be welded onto the frame and my installers had no issue with doing this. They did weld the adjustable sleeves together instead of using the bolt to tighten them together. Also had the receiver part of the hitch welded to the trailer bumper for extra support. Product is well made and the paint has held up well with no visible rust after over one year of use. Remember to paint over the weld areas. etrailer purchase was no issue and delivered on time.

Product is still holding up with no issues after one year.
by: David07/22/2019
I needed a trailer hitch for the rear of my 5th wheel toy hauler. I found this company on-line and after reading some really positive reviews I ordered one. The website was very easy to use, especially for a computer challenged user. E-mails came quickly that my order was placed and then shipped. The package arrived quickly. First thing I noticed was box was kind of, well not falling apart but kind of. Extra tape was used on both ends. When I lifted it I realized why, this thing was HEAVY! After cutting the box open and inspection I was really impressed. The paint looked good. I inspected the welds and they looked very good, very NICELY done. I will be taking my 5th wheel and this hitch to a local trailer shop for install. Overall I am very impressed with the on-line ordering, the hitch exceeded my expectation. I will be towing a small open trailer with my Side by Side on it.

Yes it’s been a year since I bought this hitch. I had it welded on the rear of my toy hauler. The shop I used made quick work of it, a job well done. It only cost $100.00 . That is as far as I’ve gotten with it. I am modifying a trailer to haul my RZR and don’t have it done yet so I have not pulled anything with it.

Did the job perfectly!
by: Jason04/25/2022
Works great for what I purchased for, hauling pedal bikes. Was able to mount upside down so receiver goes over rear bumper, keeping hitch higher.
by: Joe 05/31/2023
Well built hitch!
by: Jack03/08/2022
Bought this hitch to install on my toy hauler, worked out great. Had a mobile welder come to my rv site and install it, it allowed me to use the bike rack that I bought from etrailer.
by: Curtis O.05/22/2017
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!)
by: Les F.07/11/2016
Received the Ultra-Fab 2" Trailer Hitch Receiver for 5th Wheel Trailer Frame as promised. Installation was simple. Once positioned, clamped it and started welding. Centered the receiver and tightened the bolts then added a spot weld for backup.
by: Ronald10/29/2017
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.
by: Bruce08/18/2015
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.
by: Harry10/17/2019
We have received the package, which was in very good condition. I have recently had knee replacement surgery and have not had a chance to have the hitch installed.

Very well. It fit perfect and works great. Thank you.
by: Neil Lageman08/27/2018
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.
by: Vino Vilano01/17/2020
I had this welded to my 40’ fifth wheel and using a Kuat bike carrier I hauled 4 large frame mountain bikes over 20 thousand miles and across the worst roads the US interstate system has to offer. It worked perfect.

- Dimensions for Ultra-Fab 2" Trailer Hitch Receiver # UF35-946403I went out to our warehouse to take a look at the Ultra-Fab 2" Trailer Hitch Receiver # UF35-946403 referenced in your question. The smaller inner crosstube measures 2 inches x 2 inches and the outer crosstube measures 2-1/2 inches x 2-1/2 inches. I used a digital caliper to measure a thickness of right at 0.23 inches on both the inner and outer crosstubes. I have attached an image to assist.

It is possible to attach the hitch in the manner you suggested, but it is not rated for a bolt on application. Since this hitch isn't for towing purposes, it may function fine with a bolt on application but the drilling will bring down it's capacity. I've attached a picture of the dimensions for you.

It is compatible with I-beam, C-channel, or rectangular trailer frames. The receiver tube opening will be 5-1/4 inches out from the crossbar.

- What Size Are Bolts For Ultra-Fab # UF35-946403 Hitch?I apologize that your bolts were missing. If you prefer I can have them shipped to you. The bolts that come with the Ultra-Fab # UF35-946403 hitch are 3/8" diameter X 16 coarse thread. The bolts only hold the extension arms in place while being welded. After hitch has been welded on the bolts can be removed.

- Trailer Hitch Reciever Compatiblity With 2015 Isuzu NPR HD TruckFor your 2015 Isuzu NPR HD truck with lift gate, we don't have any custom fit trailer hitch receiver options. Depending on your frame, you may be able to use an RV hitch receiver like the Ultra-Fab 2" Trailer Hitch Receiver for 5th Wheel Trailer Frames # UF35-946403. You will need to check for fit and compatibility yourself as I can't confirm a fit. This hitch welds directly to the frame. I also recommend you check your owners manual for towing ability.
view full answer... - Why Isn't Ultra-Fab 2 Inch Receiver for 5th Wheel Trailers Rated for TowingThe primary reason that you're seeing the statement that the # UF35-946403 isn't recommended for towing is that we do not recommend towing one trailer behind another. Not only would the second trailer be pretty unstable, but it'd be extremely difficult to back the trailer. Finally, the frame structure at the rear of most trailers can handle up to a few hundred pounds of tongue weight (weight bearing downward on the hitch) but aren't suited to the pulling forces they'd be exposed to when...
view full answer... - Hitch Tube Dimension of Ultra Fab Trailer Hitch for RV UF35-946403The dimension you are looking for is 5-1/4 inches on the Ultra Fab hitch part # UF35-946403 that you referenced. I attached a picture that has the dimension pointed out in blue.

- Trailer Hitch that Fits 2020 Attitude Toy Hauler 3322SAG For your 2020 Eclipse Attitude 3322SAG the Ultra Fab hitch part # UF35-946403 that you referenced would be your best option although we haven't had chance to install it on an RV like yours. Since we know it can easily weld to I-beam frames and the width of the bracket is smaller there shouldn't be any issue.
view full answer... - Installation Of Ultra-Fab 2 Inch Trailer Hitch Receiver For Trailer FramesThe Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames # UF35-946403 is an adjustable hitch that will fit inside 2002 Nash 19I with I-beam frame as long as you have clearance at the rear when inserted on the inside of your I-beam. It is intended to be a weld on design, and instructions clearly state do not bolt to frame. I've attached the measurements of the ends to help. This hitch is not to be used to tow, but only for accessories.

- What is the Adjustable Width on the Ultra-Fab 2" Trailer Hitch Receiver UF35-946403Because the Ultra-Fab 2" Trailer Hitch receiver # UF35-946403 is an adjustable hitch, it's going to fit on a wide variety of trailers. As long as the frame members on the rear of your trailer are between 47-1/2" and 77" apart, this hitch will work just fine for you. You will want to measure the distance between the two beams to confirm a fit. To install this hitch you'll just need to weld it onto the frame and it is compatible with I-beam, C-channel or rectangular trailer frames.
view full answer... - Can the Ultra-Fab 2" Trailer Hitch Receiver Be Mounted Upside Down? I went out to our warehouse and measured the thickness of the L-Brackets on the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames # UF35-946403 and measured .34" or 11/32" thick. As per the second question, you are not going to be able to mount this hitch upside down as the mounting brackets that mount to your frame need to be oriented in the way they're designed.
view full answer... - Can Arms of Ultra-Fab Hitch be RotatedThe arms of the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames # UF35-946403 can be taken out and rotated so the welding bracket is on the backside. The receiver tube is 2-1/2 inches square and the arm with the brackets is 2 inches square so you can easily remove them and rotate them to the direction of your liking.

- Welding Ultra-Fab Hitch to I-Beam Frame and Length of ReceiverThe 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.

Other than that your only other option would be to remove the box frame and then mount it directly to the trailer frame.
