Have had them installed on the current Gemini and former DP. Installer will find 'the' spot on your roof to mount, there has to be space for it to land when you stow it, run the necessary cables etc. Trees are always a potential problems with any satellite. When registering I always ask for a satellite friendly space, and usually get one with no problems. Sometimes you can move your coach some in the site, but usually not enough to make a difference. You still have to be able to get to the pedestal and water and sewer connection, and clear things like posts, trees and shrubs with your extended slides, so there are a number of limitations as far as placement on any site pad. I have the wingard SWM3 system, fully automatic and HD, love it, it always works.
