Hi All just wanted to share a issue I had recently with my LS430 running on LPG. I have a boot LPG tank where the spare wheel should be and also a plastic aftermarket boot liner. This combination has caused the condensation that is naturally generated from the gas tank to get trapped under the boot liner. This in winter months then stop the dvd drive from working correctly. I know lift the right side of the plastic boot liner to let a little air circulate this resolves the problem. I do not have any leaks or issues it is purely that when the gas tank is used it generates condensation.
