Hauling a smart car in toy hauler fifth wheel

The DRVs tend to sit a little lower than most toy haulers so you shouldn't have a breakover issue. I think I would use a couple pcs of alum treadplate the length of the door and about 18" wide just to spread the weight of the tire track out a bit when loading and unloading....weight shouldn't be an issue inside as most are rated to haul #3000 in the cargo area.
