In our area, there's an automotive shop with a side lot on the main road. They charge $60/month to park an RV there. It's up to the seller to put signs on it, and deal with anyone wanting to look at it. They do make the seller sign a waiver in case something happens to their rig.
This is a main road leading to a highly populated industrial area. Pretty good turnover rate.
My BIL was going to use this facility until we discovered his rig had another major water leak. First time was fixed by insurance. Second time they totaled it. He got a little more than he planned on selling it. Good deal for him. Maybe you can find a place like this in your area.
Hope this helps. Sorry about your loss.
