We quickly learend that long term leasing the cost per chassis [around 2013] was less than 1/3rd of the daily cost from chassis depot pools and everyone was billing 2x that price to the cutomers.
As a local only operation we sere doing around 25,000 moves a year starting with Trac and DCLI recycled pier chassis, some of the DCLI still said 'Sealand' and the maintenance cost was steep.
Now we have over 600 chassis and got rid of the trash; some of the initial new milestone chassis are now on lease for over 4 years and the maintenance costs are still in line with the newer chassis. Our maintenance vendor has a roving unit that rolls through our drop yards and a few customer lots doing PMs and he is a happy as the drivers and owner operators.
99% of our business is within 40 miles of the port and we are up to 30K moves a year with around 95 port guys.
The port guys do 2,3 sometimes [when the moon, stars and the ILA aglign] 4 turns a day so flat 10:00 x 20's and misisng lights were a big problem that is now elimnated.
