A recommendation of starting at 70-80psi for the front bags is too high. Your coach is 28ft and very likely has a front GAWR of 4880lb (same as mine 1994 P-30 28ft). The GM manual air bag pressures for a 5000 GAWR are 40psi min and 50psi max. Your min is likely 30-35psi but certainly not 40psi. look inside your closet it will have the weight GAWR ratings.
As for the measurements that were previously given they are NOT what the coach should be when adjusting. They are for determining the 'Degree set' for front alignment....
With respect to checking the ride height on the P series rig it must be measured between the upper control arm and the base of the rubber bump stop (iron to iron) ignore the rubber bumper. It also must be measured perpendicular to the upper control arm. This is with the RV level and air bag pressure at max pressure.
That measurement is then used to select the degree set for alignment. Some have said the measurement is between the top of the rubber bump stop and the upper control arm. This is incorrect. It is iron to iron. And the final measurement only has to do with the degree set for alignment and nothing else.

How do you explain that.I still have the blown air bag to prove my point.
Try to make more sense in what you say to make yourself believable.
An Rv tech doesn't make an engineer.

What does you ride height measure from side to side? You should have at least 1.75 ins.

On a light 28 ft MH your springs may be fine but depending on age and miles driven the springs both front and rear do wear out and the bags alone may not be able to provide the right ride height. As Bud posted many of us had to go with a heavier duty coil spring from Henderson to lift the upper A arm off of the lower bumper stop to get the proper ride height. If it now rides nose up check the ride height in the rear your rear springs may be sagging some.
Right now I have them at 80psi. After the old bags were replaced the front end did come up noticeably. Before it looked like a hod rod with the nose to the ground. Now it is sitting just about level. I put a level inside the freezer and it's actually sitting a little nose high
