Expedition equipped L322?

Evening all.

I'm starting to think a modded L322 might be fun. I'd like it expedition equipped with roof rack, spots, big tyres etc etc.

Problem is I can't seem to find suppliers that sell all this gubbins.

Anyone know what is possible with an L322 to get it equipped really well to perform off road?

For a start, what are the largest tyres you can fit to an L322?

Thanks very much all.
