It might be nice to have on hand for boondocking and needing hot water. Kinda bulky though. Gets good reviews.
I'm on the fence. Think I'd just run the generator for 20 mins.
One benefit, besides not having to run the generator, is that you could have your showers off an auxiliary water vessel and not use your main tank.
