I don't really worry about it but the DW does. She worries about everything. That's her job.
She saw a youtube video about some couple that had a hydraulic issue and their coach started listing pretty bad to the port side. She was all worried that this may be happening to our coach and she would go out and find the Montana lying on the steel beam in our RV garage. It was keeping her awake at night. This is our first coach with hydraulic jacks.
The garage floor is almost perfectly level. It may be 1/16" to 1/8" off side to side.
