Sounds awesome! I have to admit that the foam pieces to "level" out the bedding seems like an absolute must to me having done months worth of nights in it now. you could probably get by with putting dirty clothes or towels or something else underneeth it, but without those its really a 1 inch bar across your back and legs everything 12 inches or so, might even be worse than my sofa bed! its the one mod i don't think i'd be able to live without. everything else is just icing on the cake.
they all come with 7 pin on them because trailer brakes were an option. you could chop it off or you could just buy a 7->4 adaptor for a couple bucks and be done with it. if you were carrying 2 4x4's on top of it you might actually want trailer brakes, or with a itty bitty car, but behind a tacoma or f-150 class truck its like nothing is there.
if anyone reading this thread needs a pair of the "saftey bars" for 4-wheelers - i've got an set i never intend on using since i'm a dirtbiker. i'll let 'em go for a bottle of wild turkey and shipping =p i might have a few other accessories around that i'm not really using either, i'll have to look.
