Simple hot Water Systems

[Texjbird]

If I'm able to keep and set up the Aliner by myself one of things on the " I NEED/WANT IT LIST" is a a simple and ez for me to use hotwater system.  I just googled PORTABLE HOT WATER SYSTEMS and my eyes quickly began to cross.

Does anyone have any experience or recomendations?  I think there is a area where I can rig a simple shower by cutting and hingeing part of a counter top to fold back and then put a tub area there underneath.  This way I'll still be able to use the portable counter top cabinets after they get here by moving them to another spot when I shower.

A shower build kind of like U Tuber Slim PotatoHead did in his Aliner.  Only I can't be lifting buckets of water up to countertop level.

Any ideas/info will be appreciated
