Not sure about the Grand Cherokee, but Land / Range Rover LPG's have some kits to put the LPG tanks underneath at the rear boot?
Might be worth investigating.
zirk.
yep ive seen these for the JEEP as well.....give me the boot space back...
think its definately worth investigating
It's the normal trade off between range and space consumed, I guess. Depends how many miles you need to be doing on a fill up. A tank change wouldn't be a problem. Shame you're not closer to James, Markie(No.2) and I!
I don't know how specific the LPGA certificate is no what tank was installed might need to get it certified again just for good measure.
Did it have an SGI system or mixer in the end?
