Need advice on dish network system for roof

The last owner of my coach spent the money for an in motion roof mount. Over half the time the view to the satellites is blocked by trees, mounts and such. Tried a manual aim antenna and got tired of the hit/miss of aiming and bought a carry out. Use a iPhone app from Dish to find a clear view of the satellites and plop the antenna down. Five minutes later I have access to my subscribed package. Consider you camping locations before pulling the trigger. The roof mounted probably work great in Kanas not so much in the forests and hilly areas.
