Very well constructed, heavy duty hitch. I installed this on the back of my Arctic Fox 29-5T 5th wheel, in order to haul my generator on it. I had to add some 2" square steel stock as spacers to lower it enough to clear hard parts on the trailer. Only negative is the requirement for some odd sized, large drill bits.

High quality product that performs its task without any issues.

The high quality, flexibility of a universal part, adaptability and ease of fabrication as well as installation made this product very user friendly. Also, a BIG thank you to Danielle in customer service (ext. 79394) who researched and looked until she found just what I was looking for from the shelf. Nice work ! As you look below at Warhawk, take note that this is the Hot Rod the hitch will be attached to...for the long haul.

Installed the hitch in less than a day. I bolted it to the trailer frame. I have a rack on it for carrying a generator.

The hitch is strong and durable. It does not loosen when traveling and easily holds a generator.

Curt's adjustable trailer hitch receiver worked as planned. I was looking for a hitch receiver that would be able to carry the 75 lb. weight of our double recumbent trike carrier. The camper bumper has a low weight rating and I wouldn't trust it to hold the carrier weight over the long term. I mounted the hitch assembly by both bolting it through the bottom of the camper frame and also welding side plates between the hitch assembly and camper frame. I also welded a plate between the receiver tongue and rear camper frame to minimize receiver flex. These additional plates should allow us to safely carry our two recumbent etrikes on the carrier if needed in an emergency. Total weight including carrier would be 175 – 200 lbs. Currently we carry the etrikes inside the camper on a custom rack.

Just received this for my 18' Travel Trailer and the build on this item is really strong and heavy. I have not installed it yet but it is straight forward and looks quite simple. I would definitely recommend this to my friends. Also shipping was extremely fast and i have been using etrailer for better than 10 years now as they never let me down. All heavy duty hardware is included which is not in the picture

Excellent proactive customer service. I wish all my online purchase experiences were with etrailer.com as they have superior merchandise at reasonable prices and they follow that up with outstanding customer service. I'm elated how my hitch mounted on my camper.



- C13704
by:

Fit perfectly and was as described. If you need to drill through your frame in order to mount it ... don't go cheap on the drill bits. Having a cheap oxide bit was my biggest frustration. I then purchased a quality bit and the job was super easy!

Very helpful when talking to the customer service department... The hitch worked very well. Very satisfied with the hitch..



- C13704
by:

Installed this on my 2019 Keystone Passport 2670BH for pulling a second trailer and it works perfectly. I did have to purchase a drawbar with a longer receiver so the trailer would clear the stock bumper on the camper. My campers bumper mounts wouldn't let me move the hitch further back and I didn't want to remove the stock bumper. Works great though. Very strong.



- C13704

As is typical of Curt products, this is extremely well built. Very clean painted finish. It might be a little challenging to drill the 5/8 holes for the mounting brackets as the the tubing is quite thick. I did it on a milling machine- a good drill press will work also. Otherwise, take your time and use a series of small drills to step up to the 5/8" I actually used a 21/32 as that is what it appears Curt puts in the mating part. This was overkill for my application. I put it on a Keystone Fuzion 371 Toy hauler. I have a pit bike and two beach cruisers. The mounting plate on the hauler is not designed for the full load of this hitch, but my intent is just for the bike rack.



- C13704
by:

Product was what was expected. I have not used it yet, but expect it to work well. One issue with it is in the instructions. It lists tools needed to install. It states an 11/16” socket & wrench are required. I did not own that size, so I purchased some before fully investigating size of bolts. What is actually needed is 1” socket & wrench. Big difference. So completion of installation was delayed until I could get the needed tools.



- C13704

Great quality. Follow directions and you will have no problem installing. I would recommend setting aside 2+ hours to put this hitch on if you do it solo.

Hitch is fine. Only issue is those are some gigantic holes to drill by hand. 4x 11/16" Dia, and 4x 9/16" Dia in 1/4" steel. Sheww!!! Glad I did not break my wrist when the bit grabs as it breaks thru the farside about 20+ times. Using brand new high quality bits is must! If I were 50 I would definitely pay someone to install.

Ask the Experts about this Curt RV and Camper Hitch

  • Recommended Trailer Hitch Receiver for Forest River No Boundries Travel Trailer
    For your Forest River No Boundries 19.3 NoBo, I recommend the Adjustable Width Trailer Hitch Receiver for RVs, 22" to 66" Wide # C13704. This hitch receiver is rated for tongue weights up to 500 lbs. I can't confirm your bike rack is rated for the back of your travel trailer as many manufacturers do not confirm bike racks for travel trailer use due to the excessive sway and bounce that cause additional strain on a bike rack.

    As long as your 2011 Keystone Passport 245RB has a box frame, C-channel frame, or I-beam frame that the frame members are no more than 66" apart, you can use the Curt Adjustable Width Trailer Hitch Receiver for RVs # C13704.

  • Where on Trailer Frame to Measure for Adjustable Width Trailer Hitch for RVs
    Thanks for all those measurements! There is a trailer hitch that will work great for your travel trailer, though the measurement you want to go with is from outside to outside, which you said was 70-1/2 inches. That means the correct hitch is the Adjustable Width Trailer Hitch Receiver for RVs, 22" to 72" Wide # 13703. This is a Class III hitch with a 2" receiver and 350 lb tongue weight capacity so you will be able to carry a good deal of cargo with it. For a cargo carrier on the rear...

  • Can you Use a Hitch Extender with a Travel Trailer Hitch to Carry Electric Bikes
    You can definitely mount the Curt Adjustable Width Trailer Hitch, part # C13704, on your travel trailer. I've linked to a video review of this hitch for you to look at. As for attaching the Swagman E-Spec Bike Rack, part # S94FR, to the hitch with the Curt 8" Extender, part # C45791, that can be done, but it's not at all recommended. A bike rack will have more play on a trailer than on a car. The extension only adds to that play, and there is a high possibility that you could lose...

    For your 2017 Winnebago Winnie Drop 170S travel trailer, I recommend using the Curt Adjustable Width Trailer Hitch Receiver for RVs, 22" to 68-1/2" Wide # C13704. This will give you the ability to bolt the receiver to your Winnebago travel trailer frame and then you can use a cargo carrier like # H01472 for your large cooler.

  • Can Curt Adjustable Trailer Hitch Receiver C13704 Be Installed On Rockwood 1940LTD Pop Up Camper?
    It is very possible that the Curt Adjustable With Trailer Hitch Receiver # C13704 will fit your Rockwood 1940LTD Pop Up Camper as it is a universal hitch, though you will need to measure the width of your trailers frame to be sure. The # C13704 fits frames between 22" - 66" wide so if you find your trailers frame is wider than this you will need to go with the Curt # 13703 instead as it fits 22" - 72" wide frames. These hitches will be perfect for carrying a bike rack or cargo carrier...

  • Which Curt RV Multi-Fit Hitch for RV with 66-1/2 inches Between Frame Rails
    In the description of the Curt hitch part # C13704 we have the overall width of the hitch listed as 68-1/2 inches and the max frame width it can fit as 66 inches. Keep in mind that the frame width dimensions for the hitches we offer is measured from outside to outside of the frame rails so your measuring inside to inside 66-1/2 inch would not even be close to use with this unfortunately. So you'd be best off with the # 13703 although it does have the lower capacity.

  • Mounting Bracket Dimensions of Curt RV Hitch 13704
    The Adjustable Width Trailer Hitch Receiver for RVs, 22" to 66" Wide # C13704 has brackets that are 10 inches long with mounting holes 8-1/2 inches center on center. The height is right at 5-1/2 inches tall. I've attached a video to assist. The top of the receiver tube will sit about 2 inches from the bottom of your frame but the hitch ball height will be determined by your ball mount. I've attached an article to assist.

  • Can Brackets on Curt Adjustable Width Trailer Hitch Receiver Mount to Top of I-Beam
    The Curt Adjustable Width Trailer Hitch Receiver # C13704 that you referenced should be mounted to the bottom of the I-beam frame on your trailer. This is how the hitch was tested and rated by the manufacturer so altering the brackets so that they sit on top of the frame could result in an unknown, lesser weight capacity. I have attached the written installation instructions that you can check out as well.

    The best hitch will depend on the distance between the camper's frame members at the rear bumper area. If the camper is equipped with a bumper, you'll also need to be concerned with the drop that the hitch provides, which is the vertical distance between the underside of the frame member and the top of the hitch receiver tube. This ensures that the back bumper or fascia doesn't interfere with the hitch receiver tube. The Curt # C13704 you had looked at is pretty versatile. It's compatible...
