Actually, it is sitting on the side of a small hill, in dirt/grass. The levelers are down to make inside more comfortable while we clean and detail it. It had not been moved or operated for at least 6 years, prior to this week. We are going through all the systems, or trying to, in hopes it can be sold at some point. Needless to say, I have found many issues, snake skins, active mouse nests, rotted awnings,original tires, etc. But while it is being checked, I wanted to know if it is safe to leave levelers down, and extend drivers side slides (2). (upside of hill)(only the front tires are off ground)additionally, it is a Scottsdale 35', Workhorse, with Allison tranny.Gas. Trying to think of anything that might help answers.Thanks again!
