This guy shows the brake controller output on a scope at over 30mph and under 30 mph. The over 30mph looks pretty good, but under 30mph, the average voltage drops to around 7V. Not good enough for some of the heavier trailers.

Some excellent info here. For those not into the scope-based stuff, note post #74 by boshog. He posted some excellent chart/graph-based, numerical comparisons of the 2007 Chevy 2500 ITBM, Prodigy P2, and the 2015 Ram IBC. His voltage readings match the readings I obtained from my '16 Ram 3500 IBC almost identically.
