Please help! Is this buyer of my trailer trying to scam me?

Take it to the bank and see what they say. I looked for Shippers Incorporated on the net and do not see them. The balls is in your court. Go cash the check and hold the TT until the bank says it cleared and the money is yours. They should be able to tell you right away.

PLEASE RE-POST WITH YOUR RESULTS, WE WILL BE WAITING
