Pennsylvania has always been a real pain regarding anything with motor
vehicles - I have bad experiences going back to the 1960s to prove it!
With respect to glider trailers, you either need (1) a properly signed
title from PA (or another state) AND a bill of sale or (2) a paper
trail that shows conveyance of possession going all the way back to
the manufacturer. I've done it both ways, once for each of the glider
trailers I've bought. It helped that I didn't deal with a store front
"get your tags here" operation, but rather a guy recommended by a car
collectors (who is always buying and selling things having dubious
provenance).

You might find it easier registering the trailer in New Mexico, rather
than dealing with Pennsylvania. But then, I have no experience with
New Mexico's DMV! grin
