Hybrid electric/propane tank-less water heater

We are looking for recommendations for a hybrid electric/propane tank-less water heater for our 99 Damon Challenger 310. We are looking for one that will run off of electricity when the bus is parked...

To heat 2 gallons of water from 68 degrees to 100 degrees in one minute you need
9390 watts (equal to 9.39Kw / 32040btuh )
The source
A 30 amp rig has only 3600 watts and a 50 amp only 12000 I burn about 300 on parasitic loads. See the problem? (and up to 1000 if the batteries are hungry)

Clearly I'm not doing it with 120/240 vac.
