Usually twin bed models have either a full height wardrobe closet or at least a nightstand between the beds. I think the nightstand was more an '80s thing and the full cabinet in '90s and up. It'll have overhead cabinets unless early '90s where it has cabinet beds above.
I don't believe there are any drawers underneath, but don't quote me on that. The water tank is probably under one, but both will pick up sideways (with a gas strut) to access underneath. One or both probably has a hatch door from the outside too.
The 2362 and 2652 are definitely rarer, but sometimes it seems like the twin models tend to be taken care of more than the regular full bed models.
