Don just asked me a question about the foam I listed. I figured I'd paste my reply here for future searchers/discussion. (Though I know virtually nothing on this topic - I'm copying a bit of what some RV friends did)

Sure thing. Here's what I ordered (somewhat limited based on what was on sale):
22"x36" Pudgee - 1/2" (8 lbs)
$138.65 USD 1 $138.65 USD
Discounted Overstock 32"x37" SunMate - Medium-soft / 2" (8 lb)
$61.45 USD 1 $61.45 USD
Discounted Overstock 32"x37" SunMate - Medium / 1.25" (5 lb)
$38.87 USD 1 $38.87 USD
Discounted Overstock 32"x37" SunMate FRG - Medium / 1" (4 lb)
From my notes:
22” (ish) high back
2” of SunMate Medium-soft + extra sun mate medium used for lumbar support
22” deep bottom
.5” Pudgee
1.25” SunMate Medium
Total of 1.75”
Or add 1” of extra booster for total of 2.75”
32” wide
The Pudgee stuff is optional (and expensive) as a top layer but it feels really cool (they sent me a big pack of free samples). On their site they have a page which based on your weight and preference can specify what firmness is recommended. Based on some RV friends who used in their RV I opted for medium-soft on the back and medium on the bottom (I'm 175 lbs).
