Lynx Leveler Blocks. Note if yours is multiaxle, they can also be used as a jack! I found to lift the front TT tire off the ground I need over ten blocks for the rear tire ramp, so we carry 20 (two sets).

Lynx levelers work great because you can easily stack according to how many inches you need. If your leveler indicates 3 inches you can easily figure the number of blocks needed.

I made a set of air bag levels like levelair sold at one time . Do a search under "air levelers" and there is someone who posted instructions to make them. Best way to level I've found.
I carry 6, 8 foot treated 2x10's
6 footers will work for you just fine.
I've got some of those Lynx Levelers also. They fit in their own nice little bag and all, but if the ground is a little soft they sink. And if your not camping on a perfect spot you will need three sets of them. I use them to level the picnic table.
Plus it's just faster and easier to through down some lumber and pull onto it.
