I honestly can’t remember what stove I bought, but it was a solid, twin gas burner with grill. Something like the Outdoor Revolution Twin Burner Gas Stove and Grill.

I fixed it by dropping the feet through a wooden base panel and fed a flexi hose and regulator to a secured 907 Campingaz cylinder. You can buy these in many places and get filled at local suppliers; however, I would recommend checking out eBay or the VW shows first as you can often pick up empty or partially filled bottles for £5-10, or even free. I added a stainless steel panel to the lid to protect the wood from residual heat on closing it and a chain to securely hold the lid when open.

Of course, as soon as we had the stove and fridge installed we got a caravan/campervan suitable Carbon Monoxide Detector.
