I too was shopping a slide out (truck camper) after a big rain. The slides were extended, I assume all the way. Couldn't see any water or signs of water in the rig but I'm a newbie to the whole living trailer world.
When we retracted the slides completely, a ton of water poured off the top of the slides outside (they do have awnings). Then we put the slides back out. Then i noticed some water pooling on the floor inside along the edge of each slide on both sides. The rig is about 3 years old, very little used. I really want this trailer, but the leaking turns me off. Sales rep said "its normal after rain, people put down towels, the floor is waterproof and other water runs down a tray under to a low water release valve." They sell "as is".Nice guy, but not impressed with the dealership.
Think I'm being taken for a ride. My friend said just leave it down an inch in front so the water doesn't pool. I;m kind of broken hearted. What do you think?
