Now I am muddleing through the install procedures but expect it to go pretty good. Thanks for the comments.Re: Supplemental Brake Systems - update 8/7/06As a prospective new buyer of a supplemental braking system, I am interested in the success of the latest ship level of these devices. Many companies continually upgrade their product with little or no publicity. Camping World bills the Brakepro as #1 best seller, if that is the case then it must be working very well for a lot of people. The availability of all of the documentation, userguide and installation instructions online at Roadmaster's site allows a person to make an informed decision regarding their specific requirments. Recent user experience then can be used objectively. Seemingly none of the other companies provide much documentation. They do offer after purchase support but I like to know what I am getting into before I layout the cash. If we could somehow get Brake Buddy, SMI, Blue Ox, M&G and others to recognize this and respond, it would sure be appreciated. Thanks for all the good information on this site.
