I cook a lot outside the van, using various equipment and fuels - Cobb (charcoal and spirit in. Trangia burner); Kellie kettle for water, cooking above the tunnel and without the kettle using the hobo stove bit (anything that’ll burn and create enough heat, mainly freely foraged, including dry animal dung); firebox stove using bottles/pots/pans and the grates that are with it (any fuel, like the Kellie PLUS it’s designed to fit the Trangia spirit and gas burners too); gas camping stove (cartridges).
When we thought of the Cali and found that the storage space would only fit Campingaz I was shocked at the cost and priced per mg against other gases. I bought 2 cheapish empty cannisters and swapped one for a great outdoors refil. I also researched another gas provider (can’t remember the name, but the bottles were the same as Campingaz but yellow - there’s a forum thread that I started somewhere) but there were no suppliers local to me the travel costs made it more expensive. In comparison (UK prices and availability, without any delivery costs) to all other types of gas bottles, canisters and cartridges, the Campingaz came out the most expensive, by quite a lot.
My initial reaction was to think “right, I’ll find a solution”. It really got my goat, but then when I calmed down and thought about it logically (and tethered the goat to a post) the convenience outwayed the finance, so we have a Campingaz bottle permanently in the space for it. Over the year we’ve only cooked twice in the van and done a couple of kettle boils but it’s great knowing it’s there when/if we want/need it.
The amount of cooking you do and the kit you carry very much depends on where you cook and what you cook for. For some it’s just to eat, for others it’s part of the trip/experience. For me, I like the challenge of outdoor cooking in different ways and like experimenting, it’s part of the whole camping/travelling experience for me. So, I have loads of gear but don’t take it all, all the time. We like to do a lot of pub and cafe stopovers so sometimes won’t even cook at all.
If cooking in different ways is a hobby you‘ll be happy to use up precious space and carry the weight (like carrying skiing gear, a kayak, etc). If you’re cost conscious you might want electrical solutions if you’re already paying for EHU. So, it’s really “horses for courses”.
Great to read different views and opinions in forums like this, no question’s too small or silly and you get lots help and support as well as views that may differ to yours.
