As an alternative to rhino ramps, I made 4 ramps from 2X10's, 3 layers thick. I drive up on all four. This is about all the clearance I can get in my garage ceiling with the lift and tires I have. They are solid, so very stout with no chance of collapse. It is high enough to do all maintenance work under the vehicle. Jacking, I use the rear diff or the front control arm mounts, with a jack stand under the frame rail(s)
