I have a gutted 67 Caravel
. It did not have any appliances. Starting from scratch.
I removed the bathroom - will use a portajon or hide a toilet under a cushion.
No indoor shower - but i would like an outdoor shower to save on space.
I talked to an ebay company from here in Austin - Marey heaters. They do tankless on demand water heaters. He recommended a model that was portable.
I seems like the setup i could do would be : (opinions please)
install the portable tankless water heater on the exterior, on the tongue in vented tool like box (where the spare tire goes on some). This model comes with an outlet and shower head for outdoor shower. I can also put a t in it and run a hot water line into the airstream from underneath for the sink. i would run a supply line from the fresh tank to the exterior water heater.
we will not camp in the winter - no freeze issues.
fyi - this model costs $119. vs. $500 for an true water heater.
