We did like BigBen, and put adjustable vents in the bedroom and bath (round vent on wall). Helps to balance the heat in coach. Also found front vent was to deap in floor, replace with shalower vent and that also helped alot. We didn't put those nice vents like BB, just plain old registers like what was already installed. Best of luck...
