I think most terminals don't care.
If you wont a clean truck you have to do it by yourself, and there it jumps in the next problem. As soon as you cleaned the truck another driver comes in earlier just to grab that truck.
I have finaly an assigned truck, and it took me about 6 to 8 hours just to clean it inside, then I cleaned him outside. After all this work the truck was gone. I talked then with the suppervisor of the trucks and he gets pretty upset but i get my truck back now. I just hope i can keep it for some time. This will be the last time I clean out a truck. I did this about 9 to 10 times in just one Year. So if they don't care I don't care anymore.
