Mark My Words: How level does an RV need to be?

Q. My motorhome is a 22-foot Winnebago Warrior. In my 10 years of full-time RVing, I have always leveled it to within a two-inch tolerance for comfort and the refrigerator. I am staying in Virginia and will drive it every week or so as it remains my only transportation. My question concerns the parking area I have been assigned.

This is mountain country and the parking reflects that. To level it, the left rear wheels remained on the cement. The left front had to be raised four inches, the right front had to be raised eight inches and the right rear, five inches. That was during the few days I continued to live in it.

Now that it is simply parked, I have continued to make some adjustments, lifting the right front four inches and the right rear two inches, thus allowing the front to slope down a bit. While not level, I felt it would be tolerable.

I’m wondering how much twist the chassis and coach can withstand. What would be the effect if I simply parked it on the cement despite the unevenness of the parking space? I see stored motorhomes that are parked unevenly. I remain concerned that, without some help, this is a tremendous strain on the structural elements. — Mary Anne

A. Yes, you can park the motorhome and not worry about the slant, but if you will have the coach parked in storage mode for more than a day or two, I think you are best off with it blocked up to approximately level. While you can leave it on a slant, it will have a tendency to put a lot of weight on the low side and, over time, this could cause suspension issues, depending on how severe the slant.

It is probably only a problem when the slant is side-to-side. When you park the rig on an unlevel surface and use blocks under the wheels to make it level, the suspension of the coach is not loaded at all. In fact, as far as the suspension knows, you are on level ground.

If it were mine, I would choose to park it leveled up.
