The best deal for a comfortable, back supporting mattress is without a
doubt the Paul Harvey recommended,Select comfort, sleep number air bed.

Hands down this is the best mattress for a good nights sleep without
waking up with a sore back.
Especially if you have a bad one.

I've tried them all, and the memory foam was just OK for me, nothing to
write home about.

I just have to figure out how to get the Select comfort into the Westy,
in a semi permanent manner.

One small problem--

The Select Comfort air bed I have now at home was $1600.00, and worth
it's weight in gold.

I wonder what the appropriate Vanagon size would cost.(??)
