Video Transcript for Curt RV and Camper Hitch - Frame Mount Hitch - 13703 Review

Today we're going to be taking a look at the Curt Adjustable Width Trailer Hitch Receiver for RVs. Now, this universal hitch is designed for use on RVs and motor homes. It gives you a 2 inch by 2 inch receiver opening, so it's going to be great for hauling your RV approved accessories such as bike racks, hitch mounted cargo carriers and other similar accessories as well, as well as for towing. When it comes to the maximum gross trailer weight rating that's going to be 3,500 pounds with a maximum tongue weight capacity of 350 pounds. Please note that this unit is not approved and not designed for weight distribution systems. It does feature these heavy-duty side brackets. These are going to allow for a maximum adjustability, so you can see here that these side brackets slide along that main body tube.

That way you can set it to the width that you need. It's going to feature your pre-drilled holes. That way you can easily get that bracket secured to the main body whenever you find the width that you need for your application. It's going to come with all the necessary installation hardware, and the hardware to get the bracket secured to the main body tube. That way it's steady and secure when you're ready to install it on your RV, motor home, or camper. The unit's made from a sturdy steel construction. It's going to feature a black powder coated finish which is very durable.

It's going to last a long time. It's going to resist rust and corrosion, ensuring that the unit doesn't get harmed by the elements. It's going to resist sun damage so it's not going to fade. It's just going to look good for a really long time. Now, when it comes to the minimum frame width that this can accommodate, that's going to be 22 inches. Maximum frame width is up to 72 inches, so this will work for any width between 22 inches all the way out to 72 inches, so it's a very versatile universal hitch.

It's designed to work on box frame, C channel frame, or I beam frame applications. Another neat feature about the unit is you can actually, if you have enough room at the mounting location you can actually position the tube mounts toward the front or rear, which for your application is going to put the hitch body in the best location for the clearance that you need. The unit features strong, secure all frame attachment, so that paired with the solid steel construction really helps it increase strength and overall safety. Again, your receiver tube opening measures 2 inches by 2 inches. You're going to have a 2 1/2 inch measurement from the center of the hitch pin hole to the opening of the receiver tube. It's got that nice rolled collar right there that goes around, but it does have a flush opening. Your pin hole diameter is 5/8 of an inch.

Hitch pin and clip or hitch lock, those items are sold separately, so if you're in need of those you can find them here at etrailer.com. It's also got the safety chain loop brackets welded on there. Those holes right here, one located on each side for your safety chain connections, they measure 1 inch front to back, 1 5/8 inch side to side. It's going to feature a class III rating. The bracket thickness for the side plates and for the safety chain loops, that's a 1/4 inch thick steel. I do want to spend some time just going over the measurements here of these brackets. You're going to notice that on these brackets we have four holes. Also, there's going to be two holes, one right here and one right here, so you would attach coming up that way as well. I just want to give you the measurements of those real quick. The actual bracket has an overall width measurement of about 12 inches. From very bottom to very top measured about 12 7/8 of an inch, and the mounting area right here has a height measurement of about 4 7/8 of an inch. The mounting holes up and down are separated on center by 2 inches, and then side to side separated on center by 7 1/2 inches. Then these holes here that I pointed out, center on center, those are separated on center by about 10 inches. The unit is covered with a limited lifetime warranty. Now, you need to be aware that all non-trailer loads like bike racks and cargo carriers that are applied to this product must be supported by auxiliary stabilizing straps, which are going to be sold separately. The main hitch body tube can be trimmed, so this can be cut. That way that the ends are flush with the frame brackets. After trimming you want to be sure to coat the bare metal with paint, that way it's protected against rust and corrosion. Again, all the necessary installation hardware is included, but if you want to weld this on just keep in mind that all welding surfaces must be cleaned to bare metal. That's going to do it for today's look at the Curt Adjustable Width Trailer Hitch for RVs.

Very well made. Heavy duty. Took some modifications to bolt onto I beam of my 5th wheel. The ledge of I-beam wasn't as deep as the bracket so therefore I had to install with a few less bolts. Appears that it should still be strong & hope to give it a try by towing our golf cart behind camper in the next few days. Takes some time and numerous drill bits to get the job done. 715046

Got it pronto. Just what I needed to feel safe pulling my bass boat. Very good quality and strong. Installed on a 2011 Rockwood 30' 8280 WS. The only modification was to move stabilizer jacks forward 3". 258430

After figuring out how to mount this hitch on our camper it was evident that it would not bolt up to the existing brackets. We dropped the underbelly and ground off the brackets existing on the trailer and had a welder come in and weld the brackets that came with the hitch on the trailer! We are very pleased with the hitch. We are going to use it for our bike rack and maybe later something heavier! 703203

I am reviewing the Curt Adjustable RV Hitch (13703). I purchased the Curt Adjustable RV Hitch for my Fifth Wheel Durango camper. I want to thank the etrailer staff for their assistance with this purchase and especially Kim who did some research on it to answer my questions. This is the third purchase I have made from etrailer.com and I'm always impressed with the assistance and technical information I receive from the staff. I received the hitch very promptly and in good condition. This hitch is a very sturdy hitch in my opinion. I did not find installation instructions with the product when I received it, so I went to the etrailer.com website and found the installation instructions on the product's etrailer webpage, ready to download, which I did. The installation of the hitch required more than the 60 minutes listed on the instructions page. I bolted the hitch on a box frame support under the fifth wheel, which took much longer than welding it on. I would suggest using a half-inch drill as a three-eights drill is just not heavy enough. Using C-clamps, I clamped the hitch in the correct position. I had to drill a couple of extra holes on each end of the hitch brackets due to the proximity of the manufactured holes to the edge of the box frame I was bolting it to. The bolts used are not what is listed on the parts list, which is one-half inch by 2 inches long. The bolts are actually two and one-quarter inches long, which made them too long to place inside the box frame support and be pulled through the drilled holes. I had to cut about three-eighths inch (or four threads) off of each bolt (12 in all) that was placed inside the box frame to be pulled through the frame bracket. These same bolts (4 bolts/2 on each end) also would not work when placed inside the main body tube which was bolted into the frame bracket. Trimming these bolts is what took so much time to complete the project. There is a unique way used to pull the bolts from inside the box frame support through all the drilled holes using a "fishwire'. My hitch came with two fishwires which are used by placing through the drilled holes, screwing the bolts into the wire, and pulling the bolt (with square hole spacer) through the hole from the inside of the box frame support. This process would have been much easier if I had had two inch bolts. The instructions also note that the bolts have to be torqued to 110 ft-lbs. But, it is now mounted to my fifth wheel securely and I am very happy with the hitch and how it fits my camper. Again, thanks to Kim for helping me with questions about the hitch before I purchased it. 462932

I was very pleased with the ordering process, the very quick delivery date, and the installation process. Although I did have to relocate my stabilizer jacks about 4 inches, this was no real issue. The hitch fit like a glove and I was able to install it myself. It took me a little longer than most others because I'm 68 yrs old and also have Parkinson's Disease. So If I can install it, I figure most anyone can. I've included a picture. Thanks etrailer for a great experience. 443026

I received my Hitch in only a few days after ordering and all the parts were in the box! I am 72yrs. and rather slow so it took me a few hours each day for several days to get the hitch fully installed on my Artic Wolf 5th wheel RV. The 72 inch wide hitch fit fine and looks excellent. I had no parts left over so I'm good to go. NOTE; the carriage bolt and square hole spacer system worked great for installing some of the hitch bolts inside my "box beam" where access was limited. 556020

This is the 3rd one of these I've put on my trailers. The first one I had welded on and it worked great. The 2nd one was my next rv and I bolted that one on and towed an additional trailer behind it with no issues either. The one I just bought will be installed on my new 5th wheel so I can tow my golf cart behind THIS trailer now too. I'm actually cutting off the factory installed 2 inch receiver to install this one in its place because I'm more confident in this one for towing than the beefy one installed by the factory. Great product! Fast shipping! Easy to install provided you have a drill, bits for steel, and a torque wrench. 575786

Quality product. Was shipped very fast. Installed it myself with help from a jack and C-clamp. Looking forward to hooking up the boat and go fishing. Thanks 636274

I like the product but the mounting flanges wouldn't work on my trailer. On each side of the trailer I beam there are the jacks, a bottoming out scrape protector, and then the black water tank. These are all fastened on the inside. If the flanges could mount on the outside it would work. While they can be reversed, then they stick out wider then the i beam and are too far apart to attach the main body tube as they are now wider then 72". What I am doing is welding a 1/4: 6x9 plate to the main bottom tube and then will bolt this to the bottom of trailer i beam. If I can edit my review, I will attach photos of the issue for me and my solution after it is done. Overall, I am still happy with the product. It would have taken more time and money to design my own and then take it to a weld shop. If I was able to weld myself, then I would have built a custom hitch. 469590

The product, shipping and customer service were great. Don't expect this to be a 1 hour job though unless everything is prepped. I installed on a Jayco 243 5er with a boxed frame. Some trimming of water tank cover required. Also found on this 2 in wide frame that trimming the bolts by 3/8 in. helped in fishing the bolts through. One person install, just a little longer than planned. Good heavy duty unit. 129031

Hello PaulI also happen to have a Jayco 243 RKS 5er. Mine is a 1998. My water tank is located at rear of trailer.I am concerned that the water tank would pose a problem for install. Since the frame a is a box style, wouldnt the bolts have to be 3-4 long to pass through box frame? Do you have any pics and suggestions on the install? If you could email me some pics or post them to your post that would be much appreciated.Thanks!!!

Chuck N.The bolts do not go all the way through the frame, only the outside. The bolts are fished through a hole you will drill with a hole saw on the inside at the rear of the water tank. A special fish tool is included. The demo video and instructions cover it pretty well. Also note on my original review that cutting a small amount off the bolts will facilitate fishing them through. With a little wrestling I was able to do it by by myself but a helper would be nice. Preferably someone with some mechanical experience. Good luck and be sure to pre read the instructions.Paul

I was going to install the hitch on my 2005 21 foot Ameri-lite trailer today. I watched your video on installing the hitch on a similar trailer so I had a good idea of how to proceed. Problem #1: The frame on my trailer is 2X4 box tubing. I believe the mounts are for a 2X6 box frame. I have about 1.5 inches of my side mounts below the bottom of the frame. Problem #2: It is a tight fit to get the drivers side frame mount in position because of the sewer dump. I had to remove the stabilizer legs to attempt the install. This was not a problem as I intended to replace them with jacks anyway. Since I never intend to tow double this is to be used for a luggage rack for my generator and other items. I believe for my purposes I can have a machine shop remove the 1.5 inches from the top so the mounts will fit the frame solidly. I will also have them drill a hole between the two already in place and remove a small portion of the left mount to allow for the sewer line. The rear bumper is light channel iron and I felt a bumper hitch was pushing my luck which is why I ordered this unit.?????????????????????????????? 595500

    The difference between the Curt Adjustable Width Trailer Hitch Receivers # 13703 and # C13704 are a couple things, starting with the # C13704 having a 5,000 lb towing capacity and 500 lb tongue weight capacity while the # 13703 has a a 3,500 lb towing capacity and 350 lb tongue weight capacity.

    For a e-bike rack that is rated for the weights of your e-bikes and also for the rougher ride quality found at the rear of a 5th wheel trailer we have the Hollywood Rack RV Rider part # HR1600 as the best option. This has an 80 lb per bike capacity which would easily handle your 70 lb bikes. The rack weighs 60 lbs so with the combined weight of your bikes it would weigh right at 200 lbs which would be most likely not too much for your RV hitch but you'd want to verify this by checking...

Instead the best option is the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames # UF35-946403 which is adjustable and welds onto I-beam, C-channel or rectangular trailer frames that are between 47-1/8" and 77" wide so it is perfect for your 75 inch frame, though it...

  • Can the Brackets of the Curt Hitch part # 13703 be Installed On Outside of Frame

    For your Jayco White Hawk Ultra Light 23MRB, I recommend the Adjustable Width Trailer Hitch Receiver for RVs part # 13703.

  • Will the Adjustable Width Trailer Hitch Receiver # 13703 fit I-Beam Frames
    The Curt Hitch part # 13703 is designed to fit I-beam trailer frames that are from 22-72 inches in width so in that regard it would be compatible with your 2004 Jayco 291RLTS fifth wheel. However, it will need to install on the inside of the frame though as that is how it is designed to install. If that is not going to be possible on your trailer due to the reasons you listed the only option I could recommend would be to contact a fabricator and have them make something that would fit.

    Most likely yes, but we do not have specific trailer fit info for the Curt hitch part # 13703 as it is a multi-fit hitch designed to fit as many RVs as possible. What you will need to do is measures the distance between the frame rails from outside to outside. If that distance is between 22 and 72 inches this hitch will fit and work well.
