@Sackmycook, @Bargy62 - cheers for that but, as I said, I'm not over-concerned. TBH, we generally use an small electric kettle for a cuppa when on hook up and I've also got a 227 canister fuelled Cadac Safari BBQ that doubles as a gas hob if required but that's a bit tall to be using on the van worktop. @DXX. I've used a Wallas and TBH was not over impressed. They are very convenient but the two things that really stood out for me were too long to boil a kettle and the heater is at the wrong height in the van (but we're all different).
