Is it possible to fit an additional tank somewhere on an L322 to supplement the one in the spare wheel well, just to give it a bit more range.

Sill tanks aren't uncommon on those - I'm surprised you haven't had a response to this yet from one of the many Range Rover owners on here.

Don't think we've got that many L322 owners on here, older ones maybe but not anything that new. I've never even seen under one so can't comment if there is room for sill tanks or not, although I suspect not from the amount of gubbins they have fitted.
