We just purchased from them in August 2013, and the experience was very good all around, except for the 104-degree temperatures at the time. This was our fourth RV, so we've dealt with lots of other dealers over the years, and these guys are very professional and knowledgeable, though unquestionably profit-oriented. Their prices on new units are pretty much unbeatable, though they will want to go low on your trade as well, so they are best-suited for a buyer that wants a new unit and doesn't have a trade.
Most of the complaints I've heard about them on these forums have to do with used, and especially consignment, RVs. I suspect those same units might have been a problem at other dealers too, but who knows.
They have more units on the lot than any dealer I've seen, including Lazy Days. They'll loan you a golf cart, feed you lunch, and still no pressure. Even if you're not looking, drop by if you're in the D/FW area -- it's a dealership worth seeing for yourself.
