I can't believe how many dumps are sloped the wrong way to fully empty the tanks. Can I raise the coach on one side with front and rear airbags without hurting anything. Another words raise the passenger side only?
Use the up arrow on the side you want to raise. The rear air bags do the left and right tilting.
I do it all the time. Helps get all of the stuff out.
When I have been working on waste valves I tip it the other way to make sure there is no flow in the direction of the valves. When I drain the fresh water tank I tip it to the fresh water tank drain side (passenger's side in my case).
Be sure to go back to normal leveling and wait for the travel light to come on before driving off.
Dude? What do you think happens when you raise the low side at an RV park?
FWIW I made four hexagonal plywood pads and painted them silver for my hydraulic jacks before finding out that my tires have sunk far enough into the ground that I can't use the pads under my jacks.
So yeah, I have the material on hand to make a set of wood tire supports.
I use the air leveling quite a bit when dumping or fueling. I tipped the coach away from the passenger fuel fill. Auto shutoff stopped at high speed at 89 gallons. Slow fill went to 100 gallons.
Only accurate way to double check the fuel mileage. 8.9 motor. .44 gph for the gen by the hour meter and the rest is the aquahot.
If the fuel fill quantity does not match we have a problem.
Ok. No worries. Thanks
If you have a LP refrig do not leave it unlevel for a long time. The LP refrigerator do not like sitting unlevel for an extended time.
If I was going to have a full hookup at the next park, I traveled with about an 1/8 of a tank of black water.
It sloshed around and I dumped as soon as I hooked up. Let it all out while it was in suspension. Never used additives, never had a problem.
I believe it is standard on all HWH airbag leveling Foretravels (Those in the know, please chime in) that if you do not shut off the engine. The leveling system will return to travel mode in a couple of minutes. Just be aware of that. So, shut off engine. Make it look like the torre pendente di Pisa. And your good for a max drain.
I've been around a while, and the reason the HWH automatic leveling system exists is more that people were wracking their frames by improper use of manual hydraulic jacks than the convenience. Your air bag system pretty much applies even pressure to the frame. Thanks to the ingenuity of HWH my hydraulic jacks kick down and apply an even amount of force to all four jacks before beginning to lift the chassis to some semblance of level.
FWIW, when you stand facing your refrigerator door, your RV LP fridge is more sensitive to being level from left right rather than the other way.

Unless you're moving or almost level the refrigerator should be "OFF", especially on a long grade up or down.
