I had purchased two twin and one fullsize 3" memory foam mattresses from ebay. After receiving them, I realized that the dinette/lower bed is nearly as wide as a fullsize. So I decided to cut up the full size memory foam mattress for the dinette/lower bed and cut down one of the twins to use in conjunction with the other twin as my wife and I's fullsize front bunk end. My 4yo son will have to do with a Thermarest for this trip until I can get another twin for the rear bunkend.
My mom is making the matresses and cushion covers for me. When I told her my plan with the memory foam she asked how I was planning on cutting it noting that she had had difficulties in the past cutting foam. I told ehr that I read that an electric knife was the way to go, and that I'd probably order one through Cabelas or something. She called me a couple days later and told me that my grandma had an electric knife that she was gonna give to the thrift shop, but that if I wanted it she would ship it to me. I did want it, so she shipped it out. It showed up in it's original box. The "Lady Vanity" is straight out of the 60s. It smells like an electric train motor when it runs. Anyways, to make a long story short, it cut through the memory foam like a knife through hot butter!
Here's my new mattress.
Here you can see why this is a factory 2nd as one end is thicker than the other.

I was also concerned as I approach the finish of this thing and it approaches it's final weight that the suspension could compress enough on a bump where the tires would come in contact with the underside of the floor. If this happened, it could remove the finish on the wood, thus exposing raw wood and having the potential for water damage. So I had some stainless sheet metal kicking around the shop that I cut up and buttoned on the underside of the floor above the tires. This way if such a compression were to happen, it'll polish a little stainless rather than damage the camper.
Lastly, I cut the cushions for the dinette/lower bunk, put them in place, and installed the old base for the dinette table. I reused the old dinette table. It'll work for now anyways.
