1) What's the best brake controller out there?
I routinely tow 3 different trailers. A 23ft 5'r, 24ft "lowboy" cargo, and a 14ft cargo. All tandem axles. Adjusting between them is nothing short of an art form, especially when the weight changes depending on cargo or load.
2)Does anyone manufacture one specifically designed for the Duramax line?
Thanks,wendell
