i asked about calor gas. was told that when the air changes to a certain degree it automatically shuts off as a safety  measure, when there isnt much oxygen about, and as it would be in the van, the air would change quick cos of the small area, then your heater would be off most of the night!!!

you could leave a window open a little thus supplying the oxygen required.

Thought about fitting one of those roof mounted whirley roof vents
