you mean one of these pie warmers...




There was one under the double passenger seat in the panel van when i bought it. It had been a builders van in Stockholm. It was missing the metal tins but that didn't bother me as it is the perfect size for two standard Cornish pasties. It can heat them properly from cold in 20 minutes or just keep them nicely warm all day. Lucy bought me some aluminium tins which fit and slow cooked a stew one evening which we ate at the beach. We had to jump start the van after that though...best used whilst the engine is running.
I have yet to find a good place to put it in the camper or the doka. Under the double passenger seat was definitely the best place for it.
