As I wait for warmer (and drier) weather, I'm starting to think about what updates I want to do the the CTC. So I started working on a design for a sofa/sleeper that would conceal the fresh water tank and water pump.
Currently the tank is located just as it is in the picture below and the water pump is underneath the toolbox. I did enclose the tank with a crude box made of 2x3s and some thin plywood but I don't have a picture of it.

I'm thinking of moving the toolbox to the other side and figure out a way to attach it to the wall in a way that is could be uncoupled and rolled out of the way if needed. Then I would like to flip the tank on it's side, build an enclosure very similar to the one that Karebru made in his build (awesome work by the way) and have an actual compartment for the water pump, fill dish, etc. (currently I do not have a fill dish in my CTC, I just have a make shift fill system and bring the hose inside to fill the tank.)

I want to be able to use the enclosure as a sofa which I plan to also add a removable table in front of, but if it's long enough why not make it another place to sleep as well. So i'm thinking of two pieces of 3/4" plywood on a hinge as the seat that could fold out and be used as a platform for an air mattress, or perhaps a futon mattress.



I'm looking for input for ideas on some sort of legs for the overhanging side. I've been considering using PVC legs that just get removed when in the sofa position or making legs and attaching them to hinges that would run along the back wall when the platform is folded in the sofa position and covered by cushions.
