This is my first motorhome. I have been rv'ing for 8 years. I bought a class c Jayco Greyhawk and towing a Jeep Wrangler. I got a brake buddy with the setup and I don't think the dealer had it set up correctly. Beside that point, I bought it in March of this year and just now am going out with it. Long story! I have a question on the brake buddy. The directions say I have to test the unit 5 times so that it relieves the vacuum of the toad vehicle's brakes. I have done that. Directions say that the lights should turn green if it is installed correctly. Does anyone else have one of these and did you get the lights to turn green? I don't remember that the units light were ever green when we picked it up from the dealer.
