newbie question auto levelling

I always level manually. I don't trust the auto algorithms not to lift the back wheels off the ground. if it did, I have no parking brakes!

When we first got our MH, I parked it on our driveway, which has a very slight slope to the street. I put a 24" level in the bottom of the fridge, then lowered the jacks until they just touched the ground. At that point, I carefully get the rig level in both axes as shown by the bottom of the fridge.

Then a put two of those stick-on levels, one on the bottom of the TV cabinet to show left/right level and the other on the driver's side window to show nose-up/down level.

I check the site we're given to see how far out of level it is when we're still on the wheels, then use a minimum amount of jack extension to get the rig level. When we stay at our daughter's house, their driveway slope needs full extension at the front with 6" pads under the jacks. The front wheels are off the ground and we need a two-step ladder to reach the bottom step on the coach's retractable steps.

Ours actually worked pretty good...not leveled. :B

Even with levelers, you need to be fairly level before using them.

Go to a LEVEL parking lot and set up the trailer for level using a 3' bubble level to make sure it is level L/R and F/B. Then reset the level in the system (your manual will tell you how). Now you KNOW if the rear wheels or one side are off the ground, it's needed to get you unit level.

You did not say what kind of system you have. On our BigFoot we have to raise the front jacks above level before hitting the auto. Then the fronts retract until the rig is level fore to aft, followed by the rears coming down until they just touch, then it levels side to side. Occasionally on a sloping site it will lift the tires on one side.

Is there a difference in the slope from where you did it at the dealer to where you tried it later on your own?

I saw a camping neighbor still use wood under his tires in order to get it closer to level before deploying his levelers as when he tried with without, it raise the wheels off the ground.

We didn't use jack pads at the dealer - just bought those after the first time the wheels came up thinking we needed a little more height or stabilization under the jacks.

Did you use jack pads at the dealer?
