To help level Mellow Yellow, I carry a set of these Lego-type RV
leveling blocks (
http://www.campingworld.com/browse/products/index.cfm?prodID=4155&src=SRQB
), which work just fine when moderate lift of a wheel or two is needed.
This last week, though, I needed to raise the lowest wheel about 8'',
which is more lift than one of these kits provides (it would take a lot
of these blocks, stacked pyramid-fashion, to build up a suitable ramp).
My dad used to carry a random collection of 2x6 and 4x4 chunks of
lumber, which didn't pack well and took up a lot of space, but he had an
RV with external storage compartments for stuff like that. What other
options are there?
