First and Hopefully, Only Complaint

We’ve only had our “C” (Ford 450 chassis) for a year....but have a repetitive problem. When leveling (HWH system), on uneven terrain (we boondock).....we get enough frame “Flex” that the door jambs, and we cannot open or close! Does anyone else experience this issue?
We can solve the problem, by driving up on blocks....but that kinda defeats the reason to have a leveling system!

That should never happen if your HWH system is functioning so as to be "complying with the requirements of geometry". Trying to twist the coach structure is a no-no for many reasons.

Whether leveling side-to-side or front-to-back - the lift should ALWAYS be the same amount and at two corner points so the supporting frame under the coach is not twisted.

For example:

For side-to-side - always correct by lifting both the front and rear tires on the right or left side by the exact same amount.

For front-to-back - always correct by lifting both front tires or both rear tires by the exact same amount.

Doing the above keeps the frame under the coach from twisting.

I use this approach all the time but with wooden blocks. The principle should be the same with a properly designed and operating automatic system.

Where an automatic system really shines is if coach leveling requires both side-to-side adjustment AND front-to-back adjustment. It was a challenge at first, but I finally figured out to handle this complex leveling situation using wooden blocks ... and hopefully our coach structure hasn't been compromised over the years from twisting at campsites.
