Sounds like you might have a solution, but here's another. I'd go to my local Big Box store or a plumbing supplier and get 2 lengths of PVC that telescope inside each other. There are different sizes, and pipe thicknesses that should come close. Then get a FERNCO transition fitting that will go from one size to the second you've selected.

Dont cut the PVC, Just telescope them and tighten the larger clamp VERY TIGHT. Slide the inner pipe to the length you need and tighten to water tight. When you come back from an outing, loosen the smaller pipe clamp, adjust to the new length you need and tighten to water tight. Your telescoping pipes should account for any new RV misplacement.
Thank you. I'll look into this today.
