Took the lpg tank out today, need the storage space and I will seek a better solution this Autumn.
After vacuuming up the crisps, dog hair and drilling swarf I find....

Look closely. Unimpressed to the last.
PS the bus really shifts without the weight of the tank onboard. Enough to make me question the benefits of lpg, as a small yacht-living friend said today "balance the inconvenience of stuff you can't take with you vs the fuel cost saving and the extra weight carried around"
Don't get me wrong, I love the high-octane fuel and the low cost per mile, but sacrificing so much internal volume is now unacceptable.
More re-engineering required!
