I cant speak to the colorado but I do use a blue ox plate and bar, patriot brake, a trailermate plug in adaptor to run the toad lights (diodes), and a battery buddy (diodes keeps toad batt from feeding to the coach batt) to keep the toad battery charged. I pull fuses in my jeep to keep the brake pedal signal in the toad from feeding back to the coach and use the aux 12v plug in the console for the patroit brake (the internal batt for b/u only). If I was pulling the neg toad batt cable I would run a 12 volt access to the cab for the patriot and use the batt buddy (about 1/2 the size of a pack of cigs).
I used the 7 pin coach side to 6 pin toad side cable. You will have to install a recpt in the base plate. With the trailermate wiring I went down inside the frame to the rear lights. To do the job right encase your wire run in (black) wire tubing. Total time for mechanical install was about 4 hours, and about 3 hours for wiring. For the first few months I used a light bar on the rear hitch of the toad, finally got around to the wire portion of the job. It has been problem free for 10, 000 miles....
If you get a base plate that uses lugs besure to buy a spare, never needed a spare but if you were to "lose" (someone needing it more than you) one then you are done toading.... and wally world does not carry replacements...
