There is really nothing he can do ... there is no signed contract.

Where'd you get the screwball notion that contracts have to be signed? Only
in a few specific cases (such as the sale of real property) does the law
require written contracts.

In most cases that's true but here from what he says there was no contract at
all oral or otherwise. Without any mention of compensation for the use of the
trailer it's a loan.

A contract exists here - and will be enforced - for several reasons: Unjust
enrichment, usual practice within the industry, delay the cause of the
trailer 'renter,' and so on.

How do you figure a contract exists? According to the OP there was no fee set
for use of the trailer.
