If you go to one of the handful of larger shows, you'll probably be more likely to find what you're looking for. (Hershey, Quartzite, and probably a few others; I've never been to any of them, so can't speak from firsthand experience.)
The local show in the Burlington, VT area the last time I went had, as I recall, one class A (or maybe it was two), one large class C, two class B's, maybe a half dozen small trailers such as teardrops and popups and A-liners, and a few dozen each of travel trailers and fifth wheels. There were trailers all over the place, trailers and trailers and trailers. I don't remember there being a single truck camper. There were a few things I liked (some clever bunk arrangements) and a few more that I didn't care for at all ( kitchens with no counters and no ovens, bathrooms and fridges that appeared to be inaccessible with the slides retracted). Especially popular seemed to be having many and/or large televisions; I guess a lot of people must enjoy traveling in order to watch TV in a another state.
