Hi all,
Planning a trip, wife and I, and have purchased a two burner gas cook top, which also has a grill.. Trip will be about 3 weeks camping. My question is, on the cooker it says it uses 19mj an hour.. I presume this would be all burners flat out on high..If we boil the Billy's twice a day, and cook a feed at night, would a 4kg bottle last the trip? Was thinking of taking a 9kg bottle, but if I can get away with a 4kg, would be lighter load on the roof, easier to lift up and down.. Any body able to do the maths, or advise? Thanks.. Odog n Sue

A 4kg cylinder lasts me for 6 weeks at least with a 2 burner gas stove without grill .

Burners are probably bigger than yours as they are regulated cast iron barbeque type circular burners about 13MM in diameter.

Take the 4kg. It will last a fair while and on a 3 week trip I'm sure there will be more than 1 occasion where you have to drop into town and resupply, just get it filled then if required.

There is no need to haul more gear than you need 'just in case'.

I've just been playing with some numbers:

At home we go through a 40kg cylinder every 3 months. That runs a 4 burner stove, BBQ and instant gas hot water for 4 people and warm washers for our clothes.

So running all that gear in a 3 week period our place would use 9kg of gas, so 2 people living off a 2 burner stove, you should have gas to spare by the time you come home.

Okay, 1kg of gas equals 49Mj, so if you have 4kg, you have 196Mj available, if your stove uses 19Mj per hour you have 10.5 hours of stove use if using all the burners, It is now up to you to work out how long it takes you to cook your meals.

I've heard you can boil the billy above the grill, while toasting your bread.. How many days did you get out of it?

i used to get 3-4weeks out of a 4kg without using the grill.

Before getting a second 4kg bottle, i did the oppositre as Odog, I used to lean the bread up against the kettle dropping it onto the element after the kettle had boiled.

After enjoying toast agin with the second bottle i felt paying swap&go fee in remote locations, just about every fortnight rather than paying a hardware half the amount every other fornight (thus 75% cheaper), was more bothersome than leaning my toast against the kettle, so i went back to leaning my toast against the kettle...

until

With the savings I bought a canister stove and a element stove-top toaste maker, then ditched the second lpg bottle...

My last vehicle I had no installed gas, just the portable stove and a proper place for it...
It's more expensive but the convience, versatility and compactness it very very good...

My next vehicle I hope to have a diesel stove..... Gas scares me...

Thanks, that's great to know, I'm keen on only carrying the 4.5kg bottle.. So think that will be good enough to last the trip.. Cheers for that.. Odog
