I had a 2009 Open Range 385RLS. It had an 85 gallon fresh water tank. Luckily they placed it right over the axles. When it dropped it didn't go far enough to break anything. Seems a factory worker took it upon himself to use the same self tapping screws they use to hold the coroplast up to screw the metal strap tank supports to the frame. It was pretty evident this was not as designed when I saw the drilled holes in the frame an inch from where the screws pulled out. I easily installed bolts in the holes using the same straps and never had another problem.
