What's the max payload? I remember looking and thinking there was no way with a 2 man setup + 2 men.
Edit: just checked and it's 660kg.
400 litre + tank and frame - 450kg
Hose reel + hose - 30kg
Couple of poles + brushes - 15kg
Fuel - 30kg
Various trad bits and pieces - 10kg
You - 75kg?
Total - 610kg
It's gonna be too tight with just a 1 man setup, no chance of a 2 man setup and this doesn't include roof rack and ladders etc.
