Where I dry camp at Richmond for the nascar race, it is very un level from
Front to back. I level my coach until it stops and I get the excessive slope light. I can tell I'm level right and left but my rear is definitely lower than my front. I put the slides out and had no issues. It rained really bad the first night and my rear sunk into the ground. I left my slides out and retracted my jacks and then placed Moore blocks under the rear and re leveled the bed it would do all with the slides still out. Never had any issues with the slides rocking or moving and have camped a dozen times since then with no issues with my slides. I did notice the same thing that once level you can not auto level unless you retract all. You can tweak them though manually.
