Update:
Tomorrow they are delivering the Motorhome from Tucson.
I have a fairly steep driveway,
I think that my name should have been "Rube Goldburg", (known for unorthodox and unusualy complex solutions for gadgets).
After careful measurements, actually guessing from the pictures and published specs, I have designed a mobile leveling ramp with enough strength to support the front of the RV in my driveway. It can also double as an industrial size skateboard.
If I can design and build Mobile Hospitals a Mobile Ramp should be easy.
I connected the two ramps because I was concerned about the stability of having ramps that are 12 inches high tipping over when I pulled up on them.
The skateboard is for moving them from the garage and back.
The picture of Kelly's TT is to show how steep the driveway is.
The Class C has a wheelbase of 212 inches and the distance from center of the tires up front is 69 inches. I used a line and a level to measure the drop and came up with 12 inches of lift needed.
