How to Install the Curt Adjustable Width RV Trailer Hitch on a 2017 Forest River Rockwood Mini Lite

Speaker 1: Today on this 2017 Forest River Rockwood Mini Lite Trailer, we're going to review and install the adjustable width trailer hitch receiver for RVs, part number 13703. This is what the hitch looks like when it's installed on the back of our RV, here. Notice, it does sit pretty far back, due to the construction of the trailer. With our opening, right here, we got plenty of room between the bumper and the hitch. That will give us a lot of room for any accessories you put into the hitch.As you can see, here, a customer has another hitch mounted to this tube, right here. However, the problem he's running into is that his accessory is too heavy and it's actually twisting his bumper as he goes up and down the road.

This is a very good replacement for that problem.The weight capacity on our hitch is going to be rated for 350 pounds, which the weight pushing down on the hitch, like here. If this was on a motorhome, you could actually use this for pulling a trailer, and it's got a pull weight of 3500 pounds. I'll give you some measurements that will help you out in selecting some accessories. From of the receiver opening, down to the ground, will be about 19 inches, and from the center of the hitch pin hole, to the edge of the bumper, not counting the spare tire, if you have one, is going to be about nine inches.Now, our hitch is going to be a universal fit. It does require some drilling, in fact, you're going to drill about eight holes, counting both sides, and then two more for the hitch to your brackets.

This is a universal fit, so you can also use this on other recreational vehicles or motorhomes. You can see on our trailer here, this works quite nicely with the I-beam construction of a trailer frame. On other trailers, if you try this out, this will work on C-channel frames as well as box frames, as well.The first part of our install is we have to get underneath the RV, and there's an under panel at the very bottom, you have to remove to get out of way, so you have easy access to the frame on the inside. These screws that hold the panel in place require a three-eighths socket. We'll remove them all the way across, taking this piece off.

Now we'll make our way down the side of the frame, removing these fasteners. Now these fasteners are using a Phillips head bit, so it comes off pretty easy. There's a mixture of fasteners on this trailer. Sometimes the fastener they're using here is just actually just shot into the steel, so you have to break the head of it and reinstall a new fastener in a relatively close area to it.We'll continue on, going all the way down the side, probably about three or four foot. We'll do this on both sides of the trailer.

We have this fitting, right here, that we have to loosen up. It's just got some screws holding it in place, as well. We'll be using a three-eighths socket to remove them, and we'll temporarily move this out of the way. We'll take this panel, now that it's loose, and we'll simply push it down and out of the way.Let's take one of our brackets, that come with the hitch, and do a quick test fit to see if there's anything in the way. We'll look at the passenger side. This bracket is intended to sit up on the inside edge of the I-beam, here. We'll hold it up against it and then slide it back as far as we can, to give you an idea where it's going to mount up at. We got plenty of room, here, on a passenger side. On our driver's side, here, we got the wire harness in the way. So I'm going to use a three-eighths socket one more time to remove it.We'll just let that stay loose, for now, and leave it just like that. We'll double-check with our bracket to make sure it fits okay. Okay, it looks like we've got plenty of room to install it. Let's grab the center section of our hitch and put it loosely into the end brackets. We're just going to slide them in loosely, just like that, for now. We'll do the other side, as well. Let's take our hitch down and grab an extra set of hands. We'll carefully pick it up, slide the brackets into the frame, and make sure it doesn't come off the center section, and we'll clamp it in place using some clamps. There.Now, when you put this up there, we'll try to slide it as far to the back as possible. If you look on the outside edge of the frame, you'll see this gusset, here. This may get in the way of the holes that you drill for the hitch to come out this way. To make room for that gusset, I'm going to take the hitch and scoot it back about one inch. Still get us pretty close to the gusset, but still have enough room for hardware. Once we're satisfied of the position of the hitch on our trailer, we'll go ahead, and mark, and drill our holes out, here. I'm going to use a 17-32nd drill bit, which will help us center it best into the existing holes of the hitch.Just enough to find our center, I'll drill my pilot hole. The pilot hole could be anything, like a quarter inch, or so, like that. Then come back at it with the same bit. With one hole drilled out, to make things a little bit safer, so I don't have to rely on the clamps anymore, I'll go ahead and put some hardware, one on each side. We're going to use the supplied carriage bolt, the block, put it through, and on the other side, we'll get another block and a flange nut. I'm going to repeat this process for the remaining holes going into the side of the frame. We'll end up having to orient our blocks, like this, to make sure that they don't overlap each other, as well as, make room for our gusset, right here, too.All my hardware on the side plates now loose and installed, so we can still maneuver the center section of the hitch, left and right, so we can center it on our trailer. Once you have it centered the way you want it, I also measured on the outside edge to bracket, to those hanging out a little bit, make sure that's even, as well. Once that's settled up, going towards the bracket, here, you see four holes. There's one, two, you can see right here, three and four. We're going to use two of these four holes, on each side, to install our hardware. We'll mark and drill our holes before. We'll drill it out with a quarter inch bit, back to our 17-32nds bit, all the way through the tube, here. We'll use this on here, and I'm going to use one on the bottom, as well.We have one piece of hardware installed, right here. I'll show you how I do it. We use the supplied bolt leader. I'll push it through the hole and out the end of the hitch. Take one of our blocks, slide it into place, and take our bolt, thread that on. Take the bolt, this is the trick, slide that onto the bolt and then make sure it stays ahead of the bolt as you rotate it pushing in. As long as it stays at the head of bolt, you can barely get this through. Again, our block will go into place, and then our nut. We're done with our passenger side, and repeat all of this hardware, exactly the same, over on the driver's side.With all our hardware installed, now we can go ahead and tighten down the bolts. We'll use a three-quarter inch socket and then torque them down, as specified in the instructions. Last thing we need to do is put this underbelly panel back into place. I roughly did about four inches wide by, about, 15 inches long cut, and I'll tip it over the tube of the hitch and put it back in place. This part will make room for this part. Reinstall our fasteners, working our way towards the back. Don't forget to put our line back up into place. We'll work all the way around and we'll be good to go.That will finish it for the adjustable width trailer hitch receiver for RVs, part number 13703, on this 2017 Forest River Rockwood Mini Lite Trailer.

I have a 2014 Sabre 34TBOK-6 platinum edition and my question for you would this product will fit on my 5th wheel because I have a ATV that I want to pull around and hit the ATV trails and go camping too and my folks have a side by side and and another question for you is can I pull a 7000lb car trailer behind it all I’m doing is to put ATV and side by side on the car trailer.

The Curt Hitch # 13703 will fit frames that are 22" to 72" wide. This is a universal fit product so you would need to check the frame measurements for your specific application. If it does fit your frame measurements then that's great, but you'll also need to reach out to your manufacturer to see if they will give you a safe weight rating for towing another trailer behind your 5th wheel. As long as your ATV, side by side, and car trailer doesn't exceed the 3,500 lb weight rating then this hitch will meet your needs. Some other things to keep in mind are that not every state allows double tow setup, and you need to make sure that your truck is rated high enough to handle the extra weight as well.

@JonG Ok thank you I have a Dodge Dually.

Is the hitch, part number 13703 the right hitch for my Heart Land Prowler 5th wheel trailer? The frame, from outside edge to outside edge, is just over 70 inches.

As long as it fits inside the 22" - 72" wide frame width requirement then the Curt Hitch # 13703 will fit just fine.
