Pam,
Im not sure the cold weather is ever going to leave. Schools are out here for the next two days so we should have packed up yesterday and taking a 4 day trip!
Im not an expert on the drivetrain, but I do know the tag does not completely raise. When I got stuck in the previous snow storm, I flipped the switch to Add trac and the tag dumped the air making the rear of the coach sit down. So Im guessing if you flipped it the other way it would raise? Hope I don't ever need to find out!
Also, from all the storms we have had and power outages, It sure is comforting knowing I have a dependable coach only 3 miles away and is there when we need a place to stay!
