Hi adjuster! This was the first I noticed your post; -sounds like you're gettin' 'er done!
Tire blowouts in the rear are definitely destructive; everyone prays it won't happen to them.

I've thought about somehow getting a big sheet of 1/8" aluminum and forming a huge inner wheel well, perhaps sheet metal screws to hold it up in there.
Just seems that something more substantial is needed than just the cabinets and/or thin sheet metal that's in there.
Hey, is this a market for an rv safe product or what?
