All depend what you class as mud, I got rained on on the way home from the dealership which made the paddocks a little bit muddy when I got there but it wasn't serious off roading just a bit of mud on the wheels.
Does a busted windscreen by a V8 Supercar when the truck was 3 weeks old count?
lol
I use the truck on a racetrack and its first meeting was the V8 Supercars. Second race of the day and there was an "incident" going into turn 2 with us in hot pursuit and I copped stones all over the front of the truck
