I just had a Winegard installed on my roof and I haven't had any problems with RV parks and big trees yet. They all seem to be very accommodating and there's been at least a couple of sites that work, Picacho AZ, Las Vegas NM, La Junta CO. Pueblo CO. North Platte NE. If big trees are an issue with reception, are you even going to fit in a space with out scratching your LM. My BIGHORN is 41.3 and that has been my major issue with the shady sites.
The problem with the little portable dish is they don't always pick up the complete programming package. I'm a full-timer and I've got Dish, if I wanted the premium channels or HD I had to go to the rooftop or the little portable mount but again then you have problems storing it and to aim it and if you're by yourself like I am it's going to take a lot longer. Its pretty easy to just turn the unit on and have tv.
By the way Adventurerv.net has the best prices for the satellite.
No problems except when to stow it in high winds.
