I just finished installation of a Brakemaster system on my Ford Ranger and coach. Once you get everything identified, if you understand minor mechanical principles, it is not hard at all. Just be sure any air lines you run is either protected by a covering or fastened in such a way as not to abrade.
Check eBay for used units, that is where I purchased mine and found another for a friend for less than what I paid for mine.
I would recommend that you also purchase the breakaway option as well.
We are heading out tomorrow on our first trip with ours.
Good luck with the install. You can do it!
