Leave a Coleman Single Burner in Ammo Can in truck with fuel bottle and and some matches and a lighter and Stanley Kit.
I leave tea bags and a some sugar in ziploc in the cups. Put the fuel bottle in a heavy sock so it does not make noise.
My MSR is an original, or second version. Dad bought it back in '76, and I appropriated it at some point before '80. I know it was bought in '76 because the receipt for it is in the box it is stored in. If I had a mill, I'd make a small aluminum pump for it. All I've done with it so far is replaced some old o-rings. I need a new flint and flint spring, but matches work fine.
If you want something you can cook on and safely use year-round get a remote canister stove. You can invert the canister during winter so you get liquid first instead of gas. A larger support base will also be better for larger pans/pots and the flame should be adjustable. JetBoils are great for boiling water (or meals based on boiling water) . They're also great for burning food. I used to write reviews and teach ultralight backpacking courses for Backpacking Light so I got to use a lot of options in the field.
I picked up one of these little gems too, in April and have used it about 6 times so far and you can't beat the price/performance. I have since bought 3 more, 2 for my boys and one for a "go-kit"/emergency pack. You can't beat the price and so far it works great!
I also have a 30 year old Whisperlite that works great, with some periodic cleaning. For longer trips in the back country this is my go to stove. I think the weight, fuel, performance is excellent for this stove. Besides a little white gas can really help in getting a camp fire going at night!
No first hand experience but my spidey sense tells me the heat exchanger would make a significant difference in heat transfer leading to better fuel efficiency.

I just got one of these from Amazon. Tried it out this morning for french press water and an egg in a tiny skillet I accidentally bought. It did great at low heat with the egg. Took 5:20 at full blast to boil 1L of tap water in an aluminum cup. I can't recall if that's better or worse than the alcohol stoves I timed earlier this year. Pretty cool little item.
