Just standard priceing,some are painted company colors some are not.They are not usually that bad dirty any good truck wash soap will do.
Sometimes ya'll pick up the account to wash all their sevice trucks plus wash the big tanks once or twice a year.Hope you like smelling propane cuz your going to get a nose full.Its sort of scary at first,looking at that big tank,smelling the propane,pw running,starting your truck hoping it don't backfire for the first time.You will get to wondering if standard price is enought before ya get done,if you smoke you better smoke alot before you get there cuz you want while ya there unless you brave.A good study wind helps keep the smell down................C-ya
