89 e350 motor home rear end question
 

Hello, I'm trying to put super singles on the rear end of camper to replace the dual wheels....I drive this camper on beach and alot of the 2wd campers have super singles on rear end so I'm curious on the they do it. Do the put longer studs in? Or is process a little more then that? I'm also unsure where to post this question. Any help will be greatly appreciated
