One of these days though, one of us engine on while we refuel plus have the refrigerator on propane while not using chemicals in our toilet no slide brake using people are going to have an accident and all hell will break loose! There will be slides slud, bars askew - it will be a mess, and we will all reform.
And then we will all have to take our RVs to get repaired when we all forget to take the bars out.
