Jacks..front or rear first?

There is discussion on another thread about levelling, I notice some place front first then rear. I was led to believe rear went first, but in reading of thread seems I might be wrong.
I have the older Power Gear/DeWalt system which is pretty much manual, front two down together and rear two can be separate.

In past, my routine was to dump air then lower rear, leveling somewhat right &left, then touch the front jacks down. I am thinking now that my routine might not be the best.
All this assuming coach is fairly level to start.

What do you do with simular four jack system?

I have the same set up wioth regards to rear left to right and fronts as one unit. If there is a standard or advised routine I am unaware of it's existence so:

I look at my level first to see what end needs to higher to level front to back then start with it, then snug it up with the oposite jacks when level. A little tweek left to right and I am done. Different everytime possibly. If I am level front to back I am more inclined to raise the front first, then use the rear to accomodate whatever leveling is required.

The trick is that you want your coach to rotate about it's centerline when leveling side to side and not twisting the frame. If you have a single front jack, or one of the systems where the front jacks are plumbed together so one can retract freely if the other extends by an equal amount, then you can easily prevent frame twisting by always keeping the front suspension off the stops during and after leveling. This means extending the front first, and always extending it more after they hit the ground than you ever extend either rear jack individually for side to side leveling. You can always check after leveling to make sure the front suspension isn't resting on the stops on either side - if it is, you're probably twisting your frame.

I started out using auto-level, but it raised the rig so high, it was a long step down to the ground at the house door. My technique is now to lower the jacks until they just touch the ground and then figure out which ones need to be extended further the level the rig with a minimum of extension.

The control panel on mine has switches that move the jacks in pairs - both left, both right, both front and both rear. I guess that's to minimise the risk of twisting the frame.

I have a Lippert system and my auto level is broken.
Their instructions are front, back, then side.
I seem to get more level using the manual then I did when the auto worked.

My manual says front jacks first, so that's what I do. I have the powergear jacks with one control for the front pair and separate controls for the rear pair.

Our instructions say first side to side, then front and back.

R,
When you press RR, do your rear pair decent together? Mine do not, one (maybe left-maybe right) goes down with the other hardly moving at all.... and, without visual it is difficult to know which. If I do not want to be going in and out of coach then when I feel one hit the ground, I take a guess at which and press that individual button (ex-if I think it was the left then I touch the LR button) to see if coach moves then I press other side's individual button untill I feel it hit. Not a great set-up, but what I have. If it was not for feeling I need the stabilization for slides, I would prefer to dump air and be done....assuming coach is plenty level.
Bill

I have a button for the front pair, and a button for the rear pair, and individual buttons for left rear and right rear. I generally extend the front pair until I feel them hit the ground, then extend the rear pair till they hit the ground, then adjust as necessary to get my bubbles where I want them.

In a perfect scenario I will be able to have my coach just a half bubble nose high, and a half bubble tilt to the left. That keeps the rain and A/C condensation running off the utility side of the coach, but is not really noticable when walking around or sleeping.

What he said, exactly. Front first.
