For a camper you are just going to have to look at what is available used in your area. Just a few general comments, if you go look at a camper and the weeds/grass are 3 ' tall under the camper it may not have been taken care of. If it's sitting under a carport or in a garage/barn there's a chance it has been taken care of. I don't care what brand you buy they ALL have the potential to leak, they just move around to much to not possibly leak. A good inspection is key........inside and out ! Also try to judge if the seller is honest or not this is a tough one but your gut will probably send out warning signals if it just doesn't feel right. Being a Stable Lift owner I am biased but for my Avion C11 restoration it is the best solution and I will never get rid of it. Good luck in your search.
