Rolling sump stand

I'm curious if anybody has a stand with sump either underneath/behind/ on top of tank that rolls on say casters or a tray system.
Looking to set up a sump next time I move in the summer for a 100gal tank. So it would only have to be about a 40 gallon sump or bucket, I've thought of some cool and easy designs for it, want to see if anyone has pictures or their own! Thanks

I was thinking perhaps a roller system along the base of a stand mixed with casters keeping a shelf to say level when pulling out for maintenance
