A note about full wall slides - they are heavy and tend to tilt the truck when extended. The tilt places extra strain on the camper frame.
That same full wall slide weight is retracted on the inside of the camper when going down the road (think bumps, railroad crossings, bridge overpasses).
It's just like driving with the slide out, only not as dangerous.
I would expect to see a slight crack at the lower front corner of the frame opening after a few years of travel.
Full wall slides are made to sell "big spacious" campers. I don't think the proper engineering is in them yet.
