Finally got around to making these into something usable. We put each heated pad into a sleeve which my wife made from spare fleece she had lying around. On the underside of the pad, we put a piece of cut down old camping mat which was also lying around - this insulates the heater element from the van floor. I added a connector which was also in the spares drawer.This is less of a “what have you done to your van” and more of a “what are you thinking about doing to your van”.
Our camper is great on cold evenings, as the Propex heater keeps the interior really warm. But we do find that the lino saps the heat from our feet. Common sense says that we should get a rug, some slippers or similar, but that’s boring.
So I bought a pair of universal fit car seat warmers on Ebay for £7.50 delivered.

Today we have been testing them on the workbench (ok, the kitchen surface), and they seem to work really well. The power consumption is approx 25W, so an hour or so in the evening should not kill the leisure battery too much.
Here’s one being tested. We just need to wrap them in something suitably robust, maybe with insulation on the bottom, and fleece on the top, and then add a 12v outlet at floor level for them to plug into.

Finished this little project off, more than happy with the resultBorrowed a spare ramp in my mates workshop and ran all the cabling in the van for the leisure battery and my powered undeseat sub. Ran out of time to make all the connections and fit everything but at least I can do all these from inside the van with the doors shut even if it's raining. Happy with that
