We mostly boondock and so level a lot. I carry the Lynx blocks but, like tenbear said above in this thread, nothing beats 2x8s beveled on the end. I carry them in the toad and get four tires elevated up to six inches each. Yes, they take up space but that is the price we are willing to pay to go some places we go. We normally set up for several days at a time and just find being out of level very much a pain. The shower doesn't drain properly, you sleep slanted, etc.
Staying in developed campgrounds would, of course, eliminate our "overkill".
