I read on the Atwood site, the water heaters regen 7.21 gallons of water an hour, regardless of model. By guessing, this would mean that the water in the 4 gallon WH will be ready to go in 35 minutes or so, from empty/cold to full temperature.
Due to the location of the WH, I could not see how hot coolant from the engine could make it from under the hood, through the firewall, to the WH which is amidships, then back. So, it will have to be run from the generator or shore power. Per the brochure, it requires 1400 watts. Thankfully, this is a resistance load, so a 2000 watt generator doesn't get socked in the face with a bunch of locked rotor amps when the WH flips on.
One good thing: There is an adjustable thermostat available as an option, part number 93105. Costs $31 or so on Amazon. If one uses a mixing valve and sets the temperature as high as it will go (150 degrees), it will produce more usable shower-temperature water than the fixed thermostat.
