I have been reading the other threads on this with interest. I am physically not able to move around much, so generally feel the cold more than most. My mobility scooter needs to be charged, and though I never watch TV I do like to use my laptop and also get on the internet - so my laptop needs charging, and (so far) I have not been able to source a 12 volt charger for it - hence it has to be charged via the inverter, which I know is an inefficient way of using my battery power. I have 2 x 110 watt solar panels, but my heating is blown air gas, and when parked up for a while I do seem to need to use the generator. Normally I am on electric hookup at a campsite, or parked up somewhere that my generator won't annoy others, but of course this is not possible at a rally. Everyone seems to manage their needs easily, but could someone give me exact details of their set-up so I could make the necessary adjustments. I posted on the other thread but so far no replies to my specific query.
