Jacks transfer the coach weight to other places on the bus that likely aren't meant to withstand that weight.
An old busnut, RIP, had a set on his GM up here in CCO/GLCC territory, some of us wondered how much of the later emerging bulkhead/structural issues were influenced by those jacks?
Easiest is running up on a few 2x lumber under the low corner, next is an air suspension manipulating system.
How often will you camp in mountain goat camping spots?
A set of jacks takes away your contribution to the "set-up spectators" entertainment?
Happy coaching!
