Just go to a mattress store and buy a top quality house type mattress.
This is often not an option. RVs are known for having special, non standard sizes.
Actually this is a very viable option regardless of the mattress size. Many mattress stores can order a specially sized mattress made to order! Check out Original Mattress Factory stores as just one example.
Memory foam mattresses are easy to trim. We bought a nice new 8" memory foam mattress while out on a camping trip 'cause it happened to be on sale at a blow-out price. Just used a bread knife (sharp) to cut it. Not a 100% perfect clean cut but you'll never see it again with sheets on it. This mattress has given us the best sleeps compared to our fancy expensive memory foam mattress at home. OEM standard mattresses are like medieval torture devices... :(
Sometimes you may need to reinforce the plywood or OSB the mattress lays on. They can be poorly supported underneath. Our OSB is sagging like a bowl and I've gotta get in there and install some angle iron. Solid 2x3 can work on the edge (screwed from above) but may interfere with storage in a pass-through. Or install it on the flat and maybe use another piece or two if needed.
