Contrarian alternative:
electric.
Induction cooktop, combo convection oven/microwave, slow cooker, pressure cooker, toaster, coffee maker, etc. Complemented by AC/DC fridges.
It's easier for us to use the boat's
diesel supply to run the genset when required, and we have the recharge
batteries 2x/day anyway.
I presume some inverters would
power some of that stuff, to, at least for occasional use.
Realize this may not
work for many cruisers, but since we carry 520 gals of
diesel... and since diesel is relatively common at
fuel docks pretty much everywhere... messing around with other fuels seems onerous.
