Hitch advice for 1976 TT

We're buying an old '76 TT (I believe it's a Wren SC) and I'm getting confused as to what I need to tow. I have an XTerra that doesn't have a hitch so I'm starting from scratch and am a complete noob.

I'm getting conflicting advice from a couple of local shops (non-specialty) as to what I should have installed. Are most newer hitch systems adjustable, or do I need to make sure it's exactly right from the start? I've been asked if I need a 5 prong or 7 prong electrical hook-up but the owner of the trailer tells me it's 4 prong.

I've done a search through the forum but can't find anything that lays it out from the beginning.

Any help would be greatly appreciated! Thanks in advance!

The 1976 Jay Wren TT looks to be a single axle weighing around 2050lbs. With that said, once you put equipment and belongings inside and pack for an outing expect your weight to go up. Your Xterra should have no problem towing this. You would probably be ok to have a Class II receiver installed on your TV, since Class II's are rated up to 3500lbs. Assuming your tongue weight is under 300lbs. The trailer should already have a coupler size for a 2 inch ball, since a 1 7/8 inch ball is only rated to 2000lbs. If not, I would recommend changing that and going with a 2 inch ball rated from 3,500 to 8000lbs.

plug ins. the owner tells you its a 4 prong, which is possible. If that suits the needs of the trailer then go with that. With that said, I would recommend having a harness installed on your TV for a 4 prong flat, which is very common among the small trailers your Xterra is likely to tow, and if the trailer has the old 4 prong round, use and adapter or make a pigtail to bridge the gap.

This is the easy and quick advice which will get you up and running without much fuss. However, if you really want to cover your bases and can spend the money, then go with a good class III hitch receiver, a 2 inch ball and coupler, an the standard 7 prong harness and plug in, then utilize an adapter from the trailer to the 7 prong receiver. This will give you maximum versatility for future changes and expansions.

Welcome to the forum and congrats on the classic Jayco Wren! I'm not much help with electrical stuff, but there are plenty of folks on this forum with great advice and tips like NVGun40 gave.
You can also use the search function here in the forum to look for help too.
Have fun camping!

Thanks NVGun40! That's exactly the type of response I was hoping to get. Now I'm at least marginally educated enough to talk through it to get the right thing installed. I'll follow up to let you know what I ended up with. Thanks for the welcome messages too. Can't wait to get towing!
