mist4life,
Is the rig still in the campground? Most campgrounds have rules against doing any type of major (obvious) maintenance at the campground.
Crazy idea here, but you might get an estimate for how much it would cost to tow it to your home so you can work on it at your own leisure and not have to worry about additional breakdowns along the way? I know that’ll probably be pretty expensive, but depending upon how far the trip is (where in Indiana and where in Ohio?), it might be worth the peace of mind.
Has anyone lived in it during these past years? If you haven’t seen it yet, check it out to make sure there is no water damage inside. If there is, it might be best to just scrap it. Sad, but true. Extensive water damage can spell the death of a rig.
Good Luck,
