You could install it yourself. I installed mine about five years ago and it took me about 15 hours. That was working about four nights about one to two hours a night and finished it up on Saturday. I paid $686.00 for the controller,switch,phloem & the coil unit. I had to purchase a 60 amp disconnect and wiring from the 50 amp shore plug to the controller. That cost me under $100.00, well worth the hassle. I have a 2004, 36 foot Mobile Suite and love this unit. If you can read and follow instructions you can do this. Good luck!!!!
