I think it would be safer to put the bottle in the car, a full 4.5 kg bottle weights about 10kg, not too heavy to lift, but imagine it sliding around in a roof box.
you must also take into consideration the max load on the roof bars. Most vehicles its around 50-60kg, add the weight of the roof box around 7 kg. soon adds up.
Yes, that was my first thought on reading "gas bottle" and "roof box" in the same sentence!
Pack it securely, upright, in the boot.
The 4.5kg butane bottle does take a screw-on (left-hand thread) regulator.
I've got 13kg and 10kg bottles but I just take two briefcase stoves with small aerosol gas cannisters, it's a much smaller package and just as cheap on gas if I buy carefully.
Thanks for putting the exploding firball/ car inferno picture in my head! Thats not made me anxious at all! <img align="absmiddle" src="forum_images/smiley5.gif">
as a side question, anyone who used the smaller 4.5kg butane - am i right in thinking they have the screw on regulators not the clip on ones? Anyone any issue with these or are the easy enough to screw on and off? Just thinking if im going to be cooking outside, im not sure I want to be screwing the bottle on and off every time I want to move the camp kitchen out from the side awning! I have a gas BBQ at home which uses patio gas, it is a big bottle (thats why not talking it camping) but the regulator pushes and clips on and off - really easy to use, I can see the screw on type being a pain in the rear! <img align="absmiddle" src="forum_images/smiley6.gif" width="17" alt="17">
You can add a quick release nozzle to the hose. That way the regulator stays on until you need to refill.
Myself, I wouldn't bother with butane. In the UK overnight temperatures can drop below 5 deg C 9 months of the year, butane will not vaporise below this temperature so it just sits in the bottle laughing at you
There's some waste ground about 7 miles from where I live and I noticed about 10 butane propane cylinders lying about with burnt wood / material underneath them.
It looks like kids have been trying to blow them up by setting a fire under them. The cylinders are all badly charred - but all are intact - no sign of them bulging or distorting due to heat from flames of fires.
Much as this alarmed me, it also re assured me as to the integrity of the cylinders.
