we finally got down to see it, and it has an issue or two, related to the slideout.
they towed the trailer some distance without installing the locking bars and as a result the sldeout has dropped about 1/2 inch at the back(lengthwise to the trailer) which is apparent when its open.
otherwise the trailer is immaculate and in great condtion, very low mileage going by the suspension system, some tire wear, but lots left and they are 2 years old, probably 1000 mles on them
im not afraid to fix anything, I just need to understand how the slide works, the electric mechanism is obvious, but what supports the weight of the slideout when its open?, the tt floor? wall bottom plate? other? it goes in and out perfectly and on the exterior appears in good alignment
