I think Roger H and Joe Z hit the bullseye in their above comments. You'll need to do a bit of research and make a few phone calls. Phone calls are free.
Apropos of my comments about rear end weight
earlier, I don't think all hitch receivers are born equal. I had mine installed at U-Haul
, got a fair price and good service. But I think the hitch is heavier than most, made of large diameter tube steel compared to some others I've seen. DrawTite comes to mind. That's just a visual comparison, mind you. But when you're hanging 150-250lb off your back end, even a 10lb savings is worth investigating, I say. And I've got a bent nose wheel to prove it.
(Note: Bigfoots are a little nose heavy compared to Casitas unless you modify your Casita's tongue, as many people do. Even a Li'l Bigfoot)
More than once I thought I should have looked around a bit more, but as a neophyte I went with a known quantity. I don't regret that part of the decision a bit. But Brian makes a good point. U-Haul
isn't special -- but they are corporate and that gives a complaint a little extra weight
, because if you don't get satisfaction you can go over the head of the guy behind the counter. All in all, it really depends on the person doing the work. Look around until you find somebody that you feel comfortable with and whose words match your research. In a very real sense, this is a decision that has the potential to make or break your trailering experience for a long time, so feel good about it and make sure you get what you ask for.
The other thing I've heard ugly stories about is the installation of the brake controller and the cable back to the 7-pin connector. I've talked to a couple of people whose cables were installed visibly by so-called legitimate dealers. Visibly as in: running the inside length of the van. on top of the carpeting. You shouldn't be able to see it, and if the dealer suggests he can't hide it, find another one because he's not telling the truth. This all may seem incredibly obvious, but sometimes (call me a cynic if you like) people take advantage of newbies. Fortunately for you, there is Fiberglass RV!
