I would continue to try and contact him before I did anything and at that time he can tell you the banks number and his load officer...From there you should be able to verify the validity of his claims and calm yourself also...If you do fax a copy then by all means put "copy" on the title copy you send to his bank...
Be very careful with this transaction is my advice also...It may be 100% on the up and up but may not be...You need to keep posting the results and get opinions...These guys have seen and heard about all the scams out there so far...
