We have had a 329BHT for almost a year now and are very happy with it. When I first saw the 336 I thought it was going to be better (the master in the 329 is pretty tight) but losing the front storage, the closet, the extra kitchen storage space, and a lot of room out of the bunk room is not worth it. The 329 is not perfect, but is a better compromise than any others that I have found.
If you do get one of the bigger LaCrosse trailers, be sure to get at least a 3/4 ton series truck, I use a Ram 2500 with the Cummins diesel and it does great. A half ton is really not enough truck.
