I've put it on top of a slide before. The only issue I encountered was when I put it on top of the bedroom slide... at 3:00 AM when DISH sent an update, it started seeking the proper satellite. A little like R2D2 right above our heads. It's on top of the rig near the rear ladder right now and working fine.
