Lilburner,
A clean truck is for city boys.
Country folk know that a truck that is used and lives on a dirt road will not be clean all the time.
I grew up on a gravel road. We washed the vehicles once a month (occasionally it had to be done immediately after a muddy trip like up the canyon too.)
The rest of the time, we just kept in mind the neighbors all had dusty vehicles too.
It's like the road to the EAA building at Briscoe Field - if you don't have the pass to get through the "regular" gate, it's going to be your city car muddy if it's been raining like it has been.
That's not what's keeping me from going (my job is), but then I have to hit a car wash the next morning.
