I've spent many a nights in trailers, but decided to buy a 99 MH and am very pleased with my purchase.
I just finished a 2800 mile trip in it to FL. Several times the rain fell fast and furious. It was nice to just pull into a rest area or parking lot, and just walk to the back to fix a meal, take a nap, or just watch TV. Traveling with a trailer, one has to get out and traverse the rain to get to the trailer, then if one forgets something, a trip back to the PU is in order.
Another thing is the higher roof, wider body (102 inch) and big windshield provide a much more open feel. Mine is a 37 foot unit, and in CA some of the parks have a 34 foot limit. Other parks may have a different limit, but I think a 34' unit would be a good compromise.
My friend is still full timing in a 28' trailer, and is loving it. He pulls it with an SUV, but spends most of his time parked in S Texas. He prefers the smaller unit as it's easier for him to get around with it. He loaned it to me right after he bought it, so I could see if that is the type of home I would want. After he sold his house, he moved into it and loves the lifestyle.
I also borrowed a class C before making my decision. They like the Class C, as they say it's easier to drive for them. After having my Class A, I definitely think it's easier to drive the A, as I believe it provides better vision around the coach. In addition, my A has a rear camera, I find it indispensable. The C I borrowed did not have a rear camera. A rear camera would be a necessity for me.
From what I've seen, there are different levels of quality among all classes of units. So actually being in one, opening and closing the doors, using the accessories; the look and feel, should make quality of the unit apparent. If you have reservations about any MH your looking at, I'd keep looking. There are plenty of good MH's out there in that price range.
As the many different units all have their proponents, and having tried the towables, the question becomes; What do you want out of a MH that you are missing from the towables?
