Thanks guys, caravan club is a good idea. Thankfully we don't really need a boat cooker as we are offshore and thankfully no rules apply to us () although most ovens have flame failure devices as per standard and as always we want to do it right. I think it really need to be a mobile home/caravan supplier but I cant find a supplier.
Thanks Paul, they are all freestanding I thought you can re-jet but again I can't find any details and yup don't want to play and I doubt anyone will do for us.. Our current oven came with both jets (Premier range) but they don't supply anymore. I should try to have a chat with a couple of people here in the marina I guess.
