When I park on level part of our drive the RR stays up all night in fact several days. If I park on unlevel part due to self leveling it lowers. This past week when this has happened its taking a bit longer to raise to height. It was a refurbed compressor fitted about 4 and half years ago so maybe time for new seals. I have a spare compressor refurbed in my box of spares so thought straight swap alas on testing with power compressor runs with plenty of output but thermal switch faulty. Can't get a reading through ,it looks US. Weird I changed this when I refurbed the compressor a few years back but now it seems duff. Ha well refurb kit ordered and at least I can sit at the kitchen table to change them
