Thanks, in part, to the sage advice I received on this forum we took the plunge and bought a Rockwood A213HW and almost immediately headed to Wyoming for a 3-day "Apollo 9" jaunt. Everything went well. Only issue was the trailer brakes coming on when they were not supposed to when we were backing sideways on an incline. I am assuming this with due to the dealer mounting the brake controller vertically rather horizontally ("to avoid the airbag"), but I will need to investigate further. I expect these kind of hiccups. A grand time was had by all! Next weekend I will begin the Solar upgrade.
