That system is for motorhomes with air brakes. Think 40 feet diesel pushers. The SMI Air force one is another controller for air or air-over-hydraulic brakes. The SMI Duo and Roadmaster are proportional brakes, just not as Direct. The SMI Duo has a pendulum weight in conjunction with the brake light signal to operate. Both the Duo and Invisibrake have their own air compressors internally to operate the air cylinder, that moves the brake pedal. That is what the Invisibrake air pressure gauge is reading, and why it draws 10 amps while braking. The Tow dolly at 1200 pounds, added to the CRV at about 3600 pounds, would exceed the bumper rating of 4000 pounds. Any weight added to the hitch to 'beef it up' would cut into available GVWR. I'm not sure what the E450 GCWR is but 4800 pounds can't be a good thing. The CRV (2011) I think, can be towed 4 down. Why use a dolly? Hope this helped. RonB with a '99TKB P.S. I'm old enough to remember Rube Goldberg.

It has a vacuum pump to assist with power brakes. Amount of braking automatically or manually programmable from RV instrument panel. Have used one for over a year on my Jeep Cherokee toad. Works great.Bob 01 23.5 TK, Jeep Cherokee Toad
