A wee progress update.
Thanks m101a1 for this awesome idea. Got the oscillating multitool and cut around the length of the liner, sliding a piece of wood between the liner and tray so I didn't go too deep. Then, worked my way around gently levering it and cracking the seal between tray and liner (thankfully, no glue/seal used there!!!). So, she's ready to lift off. Going to get a couple of extra pairs of hands and lift the whole shebang off on the weekend. Then it will be a case of flipping the canopy upside down on the lawn and dealing with the canopy/liner join using any combo of heat/braid/piano wire/wedges/orange cleaner/water blaster/whatever works! Cheers again!
