The Hopper requires the Dish Pro Plus LNB (It will show DPP printed on the LNB itself) plus the Solo Node that you currently have wired into your home Hopper setup. You can buy another cheap so you don't have to mess with the home setup.
I suggest a tripod setup like you would find at www.TV4RV.com. It's going to take some practice but since this will be the exact same thing you have on your home you will not have to change any settings in the Hopper. You just have to learn to point the antenna precisely so an app like Dish Pointer Pro by Augmented Reality will get you a large boost in that direction.
