IF the leveling-with-Legos products are durable as you guys say (and reviews on Amazon and camping retailers
are very good, too), then that sounds worth a try. I'll order some before
my next trip.
To equal my current leveling-lift ability I'll need two sets of 10...assuming bowling-pin stacking (4, 3, 2, 1). That (4 x 1") won't give me
quite the height of three 2x6s, but pretty close, and lots of times I don't need the full height anyway.
So, thanks for all the input.
RE using wooden 2 x whatever lumber:
A contractor friend with a table saw cut me two sets of three 2x10s a few years ago, and
they worked fine (other than being heavy bulky). I actually drew up plans for him using SolidWorks -- Yes, overkill, but I had SolidWorks on my computer at work, so why not?
(like the wood-grain texture I applied?)
The wood eventually cupped and split, so he cut me another set...
so cheap, why not?
Early this year I asked him for another set, and this time I specified kiln-dried, thinking that they'd be less likely to warp, and I specified 2x6s, to cut the weight. Just being 6 inches wide automatically makes them 40% lighter than the 2x10s, which is a step in the right direction...but still bulky and less than perfect.
BEFORE I had wooden leveling ramps I used natural lifts, as shown in this camping scene near the western base of magnificent Notch Peak of the House Range in western Utah:

UPDATE:
I've ordered two 10-pack sets of
LynxLevelers from Amazon.
