It would be a hard call not knowing the type trucks your biding on.

A daycab Pete is really bigger then it looks when you start cleaning,a sleeper added doesn't take long to clean.If under 15 trucks in the fleet and if they are Pete's I get 30 with sleeper and 25 without,weekly or every two weeks.
I have never seen a fleet yet that will wash every truck in the fleet whether it be weekly or every two weeks.A one man team or two can only wash so many trucks in a days time so pick your accounts wisely,let someone else have the nickels and look for the dime accounts.

When In Doubt Think It Out
