You are welcome, Nick!
Be aware that the main bed (dinette) in a Scamp 16 standard (molded fiberglass interior) is only 44 wide.
My sister has a Scamp16 Layout 6 with that 44 bed and they now mostly sleep head-to-toe for the additional shoulder room.
We had the 54 bed in our standard/molded Scamp13 and liked it. That
additional 10 of width makes it more like a double bed than a twin bed.
Currently, the only way you can get a 54 bed in a Scamp16 is to order
a Deluxe 16 with the wood interior. That is a big part of why we went with
the Deluxe that we got. As the son of a carpenter/builder, I also thought
that minor interior customization (I.e. additional shelves, etc.) might be
easier for me to do with wood.
Without the swap of sofa/bunks for front dinette in the Deluxe Layout A,
the most a Deluxe Scamp 16 will sleep is 3 (Layout B - side dinette)
We actually saw the Disc-O-Bed set up at a sporting goods store (Bass Pro, Cabelas, Academy Sports ?) and thought it looked interesting.
I dont know how old your kids are but, I think it is great to give them that
camping/traveling experience. Our own kids remember camping with us
in a Starcraft pop-up. Even though it has now been several years ago,
our grandkids still talk about the 5 people in a little Scamp13
Once again ..... Good luck!
