I'm the oddball. I have hydraulic levers and hardly ever use them. My next rv, I will be back to using wood and interior levels. Doing it that way has made lift easier for me. I don't even have to push a button now to level it.
I installed two bubble levels, one on the dash for right to left and just above the passengers head for my front to rear level. Whenever I park, I adjust my position so I'm level, then I set up my campsite around that rv position.
Since I did that I can find a level spot on most campsites and parking lots. I only use my levelers to test them , to see if they still work or not.
