FWIW-According to the manual for my coach. I make sure engine has put coach at ride height, turn off engine. Make sure the coach is plugged into shore power or the genset is running-IN EVERY CASE FOR SLIDE OPERATION. Then extend slides, I do FWS, then Bedroom and come back for Living Room one. Once slides are extended, I then turn key to acc position, and level the coach. But, since I have equalizer system, it immediately starts to lower jacks long before all the air is released from the suspension, so the coach ends up real high in the air. So, I push the auto level button, then when air starts to dump, I push the power button, this allows all the air to escape, but does not start to extend the jacks. Once air is out, I level coach manually, using a bubble level in the center of the coach as close to middle as I can get it. After several hours, I recheck the level, as the fluid has cooled, and the level might have changed some, so I do it again if needed, adjusting the "pair of jacks" as needed to raise/lower side or front. You are supposed to lower jacks in pairs and it's also supposed to be front or rear pairs, not left or right side pairs. I had Mothership check system at last visit, it's working as it's designed. I can tell you, HWH system in other MH, was vastly superior to the Equalizer system, larger diameter jacks. Those were rated at 14,000 lbs. each. In the Ventana, the fronts are one size and the rears are another size. It took me a while to get this worked out with a friends help who owns same model as we do.
