I posted a few days ago wanting to know if anyone had any advice on a hi low that is in the upright position and has been for years~ I didn't even know it lowered until a day after I purchased it....should I just leave it up? Or should I attempt to lower it? Looks like some modifications have been made near the bathroom area, and I don't know how it would lower. I worked on the camper for days, and it is in fairly good shape.....is $400 a fair price to ask? I honestly have no idea what these things are worth! Thanks!
