I also installed mine myself. By the way the same unit has been on 3 different coaches and 2 toads. The first was installed in a CG in Valdez, Alaska. It was removed when we were camping at the Davis Monthan AFB in Tucson when we traded the coach. I reinstalled it in the DMAFB CG when we got the new coach a few days later and the final install was done at my home when we got the 2013 Allegro Bus this January. The toad installs were done in AK and at home in DE. Previous toad was a Chevy Colorado. The install isn't all that difficult if you are even the least bit handy. By the way, over 200,000 tow miles on the system, and still as good as when we first put it in. We're presently in Alaska on the AF-1's 5th trip up here.
