So Far I am happy with the trailer. I've had and still have issues with the living room slide, working properly. We also have the table and chairs in our trailer and have found the the chairs are too tall or the table is to short, and its tough setting at the table without banging your leg on the table.
I'm currently busy putting shelves in the pantry and doing our customizing thing to better fit our needs.
I believe the roof is rated at 300 lbs, so you can walk on it. I've been on ours putting maxx air vent covers on and it seems solid.
