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??
