To get an idea what this might look like I drew up a 16 inch high ramp that is a little over 5 ft long. You would need 4 2x8 that are 8 ft long. (assume the 2x8 are 1 5/8 thick) for each ramp. These would be heavy.
Regardless, I would chock the rear wheels to make sure it cannot roll down the drive.
I did exactly that as you have drawn it, but instead bought a few 12
inch WIDE planks at Lowes, and then had THEM cut each piece for me. 12" willl give you a little more leeway and wiggle room as you ramp the tires up onto each new plateau. I only need a foot in height for my driveway. Back her in up to the house, push the ramps up to each front tire, and then slowly roll on up...make sure someone spots for you when you are near the top one and make sure you center your tire front-to-back on the top plateau so that it rests flat on the wood, not on an edge! Chock it well and viola! Oh yeah, those bastards ARE heavy but I solved the problem by making my wife carry them out from the garage and center them for me...ha ha?
PS: Oh yeah...additionally I use these planks when I "winter" my unit (Solera 24S) besides my house, and even in the summer when parked there. This way the rain
will easily drain off the roof from every area and not well up.
