Gary,
I'd rather see a pic of a boat up on top of your 6X6 Class C. ;)
BTW, I just came back from a lake trip towing our small aluminum boat behind our Class C. The water's edge was nearly reaching to my front driver's side door point before we could launch it on a very shallow ramp. I'm sure glad then that our rig has good ground clearance from over-size tires and a swept up rear end design!
(I'm kind of embarrassed though ... when taking the boat out I discovered the trailer's built-in shallow water launch tip-up feature. I didn't have to back out in the water nearly as far.)
