We store our Thetford dump tank on a platform built under our camper. It's been there for a year... and still doing fine. I included photos in this thread...

Approaching our home there's a steep drop-off onto another road (in a curve even). We've not had any issues with it dragging. The platform is no lower than the steps and is in the same area of the camper.
I've read where others have considered installing additional batteries under the camper. I've not done this... yet.
😉Happy Camping!
