Yep load dist hitch setups arent cheap. I belive it was around $400-500 for the one I bought last spring.
If you go and buy a new camper travel trailer style they automatically include the load dist hitch and set it all up for ya....just safer that way.
I have seen smaller SUV's like Durango, Explorers etc towing pop up campers with load dist. hitches.....dont see why you would really need one for that
