You all inspired me to look at Amazon for a 12v option, but none get great reviews.

So for now will continue to rely on a JetBoil for quick hot water. Highly recommend, I've used JetBoils for a few years on camping trips.

It makes a lot of sense to have a heating system that is completely separate from your vehicular systems. If weight is not really important, it is hard to beat a JetBoil.

Or you can have redundant batteries like I do.
/too many years of working on servers with redundant power and network connections.

I know this is a 'food stash' thread but also a Car Prep thread. My son (now 8) was born with an auto immune issue that often presents an immediate and painful bowel evacuation, (think constant state of having eaten bad Mexican the night before). And now we have a little girl.

In our van stash, along with food/water, body temp regulation, we have a little folding travel potty training toilet. It has come in handy waiting 3-4 hours at the border coming back from Mexico over holidays or stuck in bumper to bumper freeway traffic, not moving. But we have a van, it would be different if we had a sedan

I had a similar arrangement back in the day. When you gotta go, you gotta go....

If you have the space, a Luggable Loo type bucket toilet pre-packed with toilet paper, peat moss, trash bags, and hand sanitizer is a good idea.

and a poncho for a little privacy if you have to use it roadside

I keep a complete change of clothes in the car too. Many times I'm in a suit and tie, and neither the suit nor the shoes are what I'd like to be wearing in an emergency. Its nice to have in case I need to do car repairs too.

Probably even more imporant for yound kids with bowel issues.

I like to stash a jump suit in the vehicle; nice to climb into for grubby work and it will also serve to keep you nice and warm.
