Winegard Carryout GM700 Portable Shaw Direct Satellite Dish

Yes, you could caulk and screw the Trav'ler for Shaw onto the Winegard thin roof mounting plate. I don't think mounting it to wood is a good idea as it could absorb moisture which would get inside to the electronics. The biggest problems are size and weight. If you have somewhere to stow and retrieve easily, and a helping hand to get it in and out, then the only thing you have to do is run the coax(es) plus the control cable inside the coach. The controller could even be outside in a bay that has a 120V plug. You run the control cable there and you would only need to run the coax inside.
