Congrats on taking the plunge
That is a sweet looking rig,now begins all the fun of outfitting it and making it yours
My sunseeker came with a RVS system unit for rear and sideview cameras. Haven't had any problems with it and neat part is monitor is in place of rear view mirror(a natural place to look )We have a Jenson radio that includes navigation and plays dvds thru the bunk tv. Really dont use either just found the dash mount display not as convenient as a dash top or windshield mount portable gps.Do a search (upper right hand title box) for wireless rear cameras or anything else you may think of and you'll find plenty of answers. Beside the Coachman forum check out the Forester and Sunseeker forums, a lot of the discusions relate to the same fixtures you'll have in your Freelander. You'll find Amazon and etrailer.com(and other online dealers) a good source for info and a place to spend all your hard earned cash
Enjoy the journey! See you on the road
