Thanks again for the information
Seems ridiculous they would install the 7 pin connector but not provide the wiring for the brake controller. I didn't expect a built in controller, I already have a Tekonsha controller I use with my Tundra that I planned to also use on the MBS. My Tundra was pre-wired for the controller, as it had the towing option from the factory, but I had to install the controller myself. I assumed the MBS would have been similar. Shame on me for not asking more detailed questions.
Hey Forest River, what gives? Also, why can't you build a "Platinum" version of the MBS motorhome, with HID lights, fog lights, TPMS, etc. that are clearly available from MB? I would have gladly ponied up for a better equipped chassis. I chose the MBS for it's size, not to save a few $$$.
