I have been running an EAZ-Lift brand weight dist. setup with a single sway-bar for about 7 years. I think I got it from JC Whitney. They had the best price on it at the time. $250-300 If I remember correctly, and $60 for the swaybar. It comes in 500, 750, and 1000 lb. tongue weight versions. I use the 750 one, and it is alot better built then the reese 500 lb. unit that came on the camper I bought last year. The reese looks like a toy compared to this thing. I have used this thing on a 25ft, 23ft, and 18ft, campers, as well as a 20 ft. car hauler and I love it.
