Decided to have a look and see how much room the plastic tub liner took up and was very surprised by how much more room there is without it.
The long term plan is to get a canopy and drawers and do the whole set up, about to move to sunny state which is also on fire at the moment, but for now to avoid just having the bare ribs on the bottom i have decided to put down some board with more marine ply. This will also stop things bouncing around and denting up the tub when its not fully loaded.
Empty without tub liner

Start of concept

Will have some small boards for just in front of the wheel arches as well
Did have one question though. When drilling through the tub, obviously from the bottom up to avoid important things, what sort of rust prevention should i be worried about? A simple coat of paint enough or have to go and get something particular.
One last thing if anyone wants a tub liner for 20 buckaroos and they want to travel to glorious Wagga Wagga hit me up. I know the chances of this are low haha. Otherwise it will be getting cut and put in a dumpster at work.
Cheers and have a good weekend.
