I'd do the sums.I often plug in the night before I go away. Pre-cool the fridge. Make sure the batteries are topped up. If it's winter, have the heating running a bit to drive out some moisture. And if I'm going somewhere without hookup and water, I'll pre-heat the water as it holds the temperature for a couple of days and save me a bit of gas.
Either way, it's pennies. And getting the gas refilled is inconvenient.I'd do the sums.
It will depend on the cost of your gas, but I'd expect it to be cheaper than electricity for heating the water unless using Camping Gaz.
Topping the batteries up is a good idea, though. It's bound to be cheaper than generating from DERV.
HOW MUCH !!!!!

Similar to what I’ve got and the best of both worlds with the adapter I keep on board anyway

My thoughts as well. I have pondered lagging the Truma with 1" foam but I'm not sure about either safety or efficacy.What's this super water heater have you got?
A Truma Combi only keeps the water warm for a couple of hours
Not much point as the plastic cover is spaced away from the boiler, I don't think it would do much good.My thoughts as well. I have pondered lagging the Truma with 1" foam but I'm not sure about either safety or efficacy.
