my driveway has about a 10-15 degree slope. when i back out the rear of the coach scrapes the road whaen i cross the curb and gutter. what kind of ramps have you guys devised to place at the curb to prevent this?
Years ago we used to put a steel pipe about 6 inch dia in the street gutter. The rain went through it OK. May not fit your application. If it does work, you could maybe just put a couple of 2 ft sections down for the wheels to run over when you move the unit.
