Have we misunderstood the question, John?
I like the self heating food idea, stay away from hexamine or esbit whenever possible, just look up the gases it gives off when it burns.One thing I would suggest is one of those largish, plastic stacking containers to put all the kit it.1. cheaper than a bag and less likely to be used for a weekend away2. If you breakdown on the motorway you get out of the car and go to the other side of the barrier and await recovery. If it's cold the box/container gives you a nice non-conductive seat to wait on.The box also works where it's very hot as well, I've used a pelican case after the truck we were in decided to eat it's gearbox in the desert. No sand in my undies thank you!
