Wonder if anyone can help? I have a clause in my van insurance from Adrian Flux that reads "368 Fire extinguisher warranty - It is a condition of this insurance that an efficient fire extinguisher is kept in your vehicle". Its a van being converted to a camper, they were no help in giving me more info so just wondered what the collective view might be. If the van is well on fire i am going to let it burn so am not looking for anything massive, also to work i suspect it would need to be maintained (annually bit like the work ones?), again any thoughts? I was going for a 1 or 2 kg dry powder???
