It's at least five times harder than going SD in your RV. I only use my setup for tailgating and my TV is only a 32" Vizio flat panel, but while I grant you there is a difference, it's simply not worth the extra issues in my case. I see you have just the one post here. I suggest you use the search function and view the dozens of posts on this subject as well. If you will be stationary for a period of time (like going south for the winter and staying in one place) then it may be worth it but if you're on the move my suggestion is stick with SD.
