How easy would it be to extend the shower-head hose? Is it a standard-size that I could find an extension for easily?

I bought 3/8th by 1/2 in diameter tubing from Menards. Swapped the hardware. And now I have a 15ft hose for my shower head. Was not difficult to swap.

can you turn the water flow off at the shower head?

No the water has to be continuous running for the heater to work.

Coleman is avoiding the GPM on this unit. my question is what else are they not telling.

I sent mine back. Coleman, flow rate was sufficient, and is largely dependent on the input pressure. YOU are the igniter for the Coleman. I chose instead to return my Coleman, and purchased a Triton on-demand. The Triton is self igniting (D cell batts) and has an internal flow sensor. So, add batteries, hook it up to a water and propane source, and you have instant hot water when you turn the valve.

Does battery disconnect for easy charging?

Only the elite model has the battery disconnect.
