Obviously your mileage may vary, but we just use a mattress cover over the existing bed assemblywith the bedding (set of double bed sheets sewn across the bottom and half way up the sides, and a duvet) directly on top. The whole issue rolls up and nicely fits into the passenger side wheel well compartment. Takes about a minute to unroll and make the bed. We generally sleep very well.Our early 2006 T1N LTV came with a foam mattress that the previous owners had. It takes up a tremendous amount of space and is only so-so. As we use a Sleep Number for our regular sleeping wondering if anyone has a recommendation for an air mattress that's comfortable?

That is what we use (tri-fold). It takes up some space, but for 2 people using the rig, it is not a problem. Fitted sheets stay on it when folded making it super fast to set up. Use have a corner bed Serenity. The back bed has the full size tri-fold that stores up against the back wall, still allowing use of the sofa (wife's quarters) and I use the front bed with a twin tri-fold mattress and it stores behind the table up against the driver's side wall. Even with that back table seat taken up, two people can sit at the table without rotating the cab seats, and it is possible for 3 to eat at the table if the MB seats are rotated around (possibly 4). Frankly, I don't need the twin mattress in the front but my wife insisted since that is the one she started with in the back before upgrading to the full size.Tri fold memory foam is wounderful. And folds up pretty small. We use ours as a couch sometimes.
