and I’m still waiting for my Truma control unit to arrive, I have taken to putting on a single burner and blowing the hot air away from the cupboards above with a small fan - very effective and I’m still alive. Only taken me 5 years to work this one out. Is it a suicidally stupid thing to do? I only do it when in seated part of van, wouldn’t leave it on while lying down - that’s the theory anyway. I do have a CO detector.
