I made some ramps using 2 X 8 treated lumber. The bottom piece was between 3 and 4 feet long. A shorter piece was screwed on top and then repeated until I had a ramp with little tiny steps. I think I had 6 layers for about a 9" rise. They were heavy too! Also, the length of the ramp that extended beneath the door and rocker area made it impossible to gain access in that area. So I changed the design to make it a 2 piece ramp. That did 3 things all at once. It allowed me to remove the ramp "steps" once the tire was up onto the flat surface. It made 4 smaller pieces instead of 2 huge pieces so it was easier to store and carry them around. Lastly, I used the "steps" portion as a wheel chock behind the rear wheels for added safety. The new lumber cost about the same as a new set of Rhino Ramps. If you have lumber laying around then it'd be cheaper. I laughed at myself for spending the money and time making then because 1 month later I found a brand new set of Rhino Ramps at the Thrift Store for $10. Joke was on me. grin grin
