if it has towbar fitted, you probably need to remove it first. On mine(same setup), the bolts at the chassis(of the towbar) interfered with getting the tanks out. Tanks came out as a single unit on a frame. Was a slightly tight fit between chassis rails, but mainly due to grimy buildup. Actually the fact that they held themselves up due to the grime/mud/etc helped to get them out as I didn't realise they weight so much as a single unit.
They did have to come out sideways(ie. not fore-aft) as the connections on the tank wouldn't allow them to drop straight down, or fore-aft. Can't remember which side the connections were, but whatever side they are, you have to lower the OTHER side first(sideays, yeah!) then the connections side comes down last.
There will be an isolator valve to shut the gas supply off(to the front of the car) which needs to be off first before you undo the pipe, or you have a ton gas expelled into your face ... or something similar.
