First of all, most all manufacturers will offer several different brands that are marketed as entry, mid, and high level as far as quality and options are concerned.
The Pioneer is the entry level model from Fleetwood so it's going to be the most economical trailer they make that will have basic cabinets, flooring, etc and an unsealed and non insulated underbelly along with a lighter frame. Forest River makes several entry level trailers that would be comparable to the Pioneer such as the Salem and Wildwood.
I guess the moral of the story is not to judge any manufacturer by their entry level stuff, because it's all about the same!
I've bought and sold a few trailers over the past couple of years and started off with the Pioneer. For the price, it's as good as anything you'll find. The next trailer was a Layton (made by Skyline) and it was upgraded with the sealed underbelly and noticably nicer fit & finish. Last Summer I decided to go with a 5th wheel and went with a Keystone Laredo and I've been very pleased with it, not only does it have a sealed underbelly, but it's fully enclosed and heated--comes in nice during late Fall!
Sorry to keep beating the dead horse named "sealed underbelly" but if you opt for one that's not sealed plan on having some guests, 4 legged guests that get into your food and crap on your pillow....
