Never mind range anxiety, I am suffering from fuel anxiety. There isn't much profit for the oil cartel boys in selling LPG – they will make a lot more money from selling electricity at garage forecourts as well as pre-divorce roses (any wife presented with guiltladen roses bought from a garage knows she's in the poo), so LPG in the UK may be on the way out.
My grand plan with the Chevy van was to run it dual-fuel on switchable LPG, which is very available on the Continent but will probably vanish from the UK. It's mostly about cost. The 7000lb van with its 5.7-litre Chevy V8 gets about 14mpg on a run
