We don't have a wave, but do full time in a regular Seismic 3712 (there are six of us, so the smaller one won't work right now). We have enjoyed moving to the toy hauler for several reasons. One, tank size. I can carry quite a bit of fresh, gray and black, which for us is helpful because of boondocking that we do while moving from place to place. I like having the built in generator as well, for the same reason. I also like that when the beds are put up in the back I have roughly the same area that I used to have in our 5 slide bunkhouse that we had before, even though I now only have two slides (less maintenance). For me, I liked adding the third axle because of stability and the extra set of brakes, but that is not really applicable to the smaller units.
Overall, I think you will like moving to the toy hauler. They have started building some very comfortable ones to live and play in.
