not any real help,
but if it was me I would be price shopping online at some of the larger trailer sites, I'd want all aluminum too
many of these larger companys will even deliver and the fact many have bulk trailers there prices can be cheaper
I know there are some larger places in states like MI< and IN
but I would have to suggest too, that you do research well before buying, as some of the larger sxs's might not fit in all the toy haulers out there
if that is a concern of your's or not??
If your "self contained" statement means an on board generator your narrowing your search for about 3 brands. And your search is going to take quite a while. I couldnt find any forsale anywhere that people werent asking for my first born. Also if you give us an idea of what yoh want to fit i can help narrow your search. I spent countless hours researching before getting our 2016 cherokee grey wolf limited. We wanted an open floor plan and the ability to haul 4 quads or 2 quads and a rzr800s.
