First class system. We've had one since we had a 2005 Diesel Bounder. We've moved it to 2 new coaches and 2 toads and it's still going strong. Nothing to put in, take out or mess with. In addition it's the only system out there that meets the Federal Motor Vehicle Safety Standards as far as hooking to the RV air system and using air for the toad brake.
THeir customer support ids great too. We broke a brake pedal actuating cylinder cable on the way down from Alaska. After a call, I sent the cylinder back to them and they replaced the cable and sent it back. Less than $30, including shipping and I had it back installed 10 days after I dropped it in the mail.
If and when this one finally dies, I'll have another one as fast as I can get it. We have over 150,000 tow miles on it an still as good as new.
