Class C leaning a little to starboard

I was taught that shocks don't carry weight, only reduce the bounce when the axle goes over a bump. I would actually get a ruler and measure the difference on a flat driveway and know for sure what it is we are dealing with. As others have said it might be normal, depending on how the rig was laid out for heavy stuff, could be a weak spring/broken spring, deflated air bag. Getting true corner weights at a truck stop is very difficult, better to find someone with scales designed for that kind of weighing.
