Side to side often helps - nothing extreme. It also helps to have the waste tanks as full as possible when you dump them. If your campsite has a water hookup, you might consider putting more water down the drains & toilet prior to dumping. Sometimes dump stations have kind of an indent that the trailer wheels fit in, which helps give you more of a side to side lean; if the CG you're staying at has a dump station (even if you have full hookups at your site), you might walk by it during your stay and see if it looks like it would help to use that, rather than dump in your site. We have often done that if the sewer hookup at our site is above-grade or has other issues that make dumping more difficult.
No really stupid questions here. Ask away - that's how you learn! :)
