R-Pod Toy support?

New here. Considering what trailer to buy as a base for starting a particular conversion. What I want to do is build a toy support trailer. This idea is similar to a toy hauler, only I will not need the trailer to haul the toys. Those will go in the bed of my truck (two dirt bikes). What I want is something to sleep in and act as a good base of operations for a dirt bike pair. Hence, support, not hauler. This will be technical for the bikes, housing for two adults (myself and my s/o), and our wonderful dog: Cosmos. I thought the relatively light weight of the pod would be great so that the total weight after the modifications would still be much lower than a straight toy hauler

I want to include some features like a fuel station (doesn't have to be 50 gallons or some such, more like 20. maybe), hose for spraying off the bikes, possibly a small air compressor, lots of water capacity if there is not enough already, generator, lots of battery power, converting the rear garage area away from a kitchen oriented/tailgating area into an actually more literal 'garage' with tool drawers, pegboard, good outdoor flood and spot lighting, etc. I was even thinking I could ditch the black water tank for a composting toilet to save weight and possibly replace that space with the fuel cell (assuming the black water tank was in a good location to begin with) Ideally I would like to strip out the wood looking interior and replace it with something more billet looking like on the old Fleetwood evolution series (another trailer I am considering for this project).

Do you think an R-pod would make a good base for this? Are they relatively easy to access? Is there enough room in storage space in the exterior, or behind the walls, to add these sort of things? Any help and input is appreciated
