I know on my camper if I don't level it i have issues sleeping, with plumbing and potentially the fridge..and keep things in the frying pan.
And if i don't put down the jacks it's like being in a boat when you or anyone walks around, amost enough to spill my beer.
I see on the big motorcoaches they have hydraulic jacks/leveling legs for this situation.
I've not seen any discussion here about it - no questions, concerns, solutions.
So..anyone do it? If so, how? If not, why not? How you keeping your beer in the glass?
