RV can’t make it into driveway. Bottoms out hard.

Recently we were shopping for a new motor home. Our driveway situation is less severe than yours but we did have to have custom ramps made to park our 40' motor home. We looked at a 28' class C (yes downsizing) but the grey/black drain was beneath the motor home about mid way between tires. We really liked the motor home but we knew there was no way we would get it in the driveway without breaking off the drain. Passed on that one. Good luck with your situation and keep us posted as to the solution.
