No, you cannot drive the coach in the raised setting. After you exceed about 5mph the HWH system will revert to travel mode. There is a work around, pulling the fuse you just replaced, BUT driving in the raised mode should only be done in an emergency. If you have an air bag leak, you will soon be driving with the coach on the tires. No bueno.
If you look inside the rear fender well at the front, you will see a 1 inch square tubing that the framework is attach to. The bottom of that tubing is the “official” ride height measurement point. It should be between 11 1/2 and 12 inches.
However, you may have identified the problem before you go adjusting ride height valves. If the coach air system will not reach 120 psi, the rear WILL NOT come up to proper ride height. You are right check the engine air compressor governor. You probably noticed a gauge close to the rear solenoid six pack. 80 psi will float the front air bags, but it takes 110 to fully float the rear. Many folks have gone on goose chases with six packs and ride height valves, when the problem was low air pressure.
