Hi Skip, Grasped the nettle and had my RX300 LE converted to LPG. Have to say that I did a lot of research and that anyone who says it can be done in a day is a cowboy! The garage that did mine also had another RX300 booked in which had already been "converted" but after inspection proved to be an accident waiting to happen. I understand he's a satisfied customer now. Check that the installer is LPG Approved. My tank holds 65 litres and I haven't had any problems with consumption or performance. Happy to give further details if required. Regards, Grandpa Al
