This youtube.com video titled offroad mit wohnkabine is unusual as you don't see people rough-house with a truck carrying a slide-in camper. I think the camper is made by Tischer and it seems to take the rough treatment. There is so little movement between the truck and the camper it must be bolted to the truck bed.
