So, we actually bought a set of the Anderson Levelers because of this thread!.
It took us a few minutes to figure out the process that would get us to level.
When we arrive, The galley hatch is opened, and a level placed on the counter top.
The large "ramp' is placed under the back of the low side tire.
The TV is backed up until we're level.
Then the chock is placed under the ramp.
We disconnect from the TV and level front to back.
And finally, the stabilizers are lowered, and any final adjustments are made.
Bingo!
The whole process takes less than 5 minutes (well under).
I fully realize that our campers are small and light, and this may be overkill (somewhat), but I highly recommend the anderson leveler simply for the absolute ease of operation.
