Re: Air leveling question
Reply #23 –
If you prefer manual leveling (some members do) and are happy doing it that way, then that's all that matters.
BUT, for the benefit of our recent members who may be new to "auto leveling", I would like to point out that the HWH automatic leveling system is designed so it should not twist the frame or stress the windshield. This assumes that the leveling system is working properly, and that the two 10 psi pressure switches on the front 6-pack manifold are functioning correctly.
IF the above assumptions are true, then the HWH auto leveling system will do the following:
1. It will attempt to level the coach by releasing air from the appropriate bags until level.
2. If releasing air from either of the front corners results in air pressure in the bags dipping below 10 psi, then air release from the opposite front corner bags will be inhibited.
3. If at that point the coach is not level, then the system will add air (using the aux compressor if required) to the appropriate bags until level is achieved, or until it gives up and the "EXCESS SLOPE" light comes on.
Since the HWH system stops lowering the front of the coach as soon as one (front corner) air bag pair is almost empty (i.e. on the mechanical stops), the coach frame should never be subject to any twisting force, and the windshield panels (especially on the GVs) should not suffer from any undue stress.
