Which is the cleanest company.

Eh, the dirtier the truck, the lighter the load you can haul. Makes a difference when you're lumping it yourself.

 

Mine gets washed at least once a week (tractor and trailer)...No matter what the weather is like.

 

In this economy I'd be wary of the ones that are all spotless. Too much time on their hands.

Inside of my (company) truck is spotless, all the time. The outside gets cleaned when I get to a terminal. The only thing I clean on the outside is glass, lights and mirrors. I the winter I try to remove built up snow and ice.

I really don't think you can judge a company by how clean the equipment is. I'd be more worried about how banged up it is. I'd be embarrassed to drive some of the trucks I see out there with bent/broken/missing farings etc. I don't care if it's clean, but if your drivers are always hitting stuff there's a problem. And if you aren't fixing that stuff, well, that says a lot to me.
