Shower and Hot Water Systems

Ive been looking into having a shower awning on the side of my new van and after looking at several different brands I came across the Quickpitch, having the most solid bracket system I could find. Im also looking at hot water systems. I dont like having indoor systems they take up too much room and when they break. Been there done that. There are several options listed below. from a Joolca portable LPG operated system. To a solar and 12volt options. Still looking into comparing whats out there, but prefer portable and easy to fix.
