K-Line panel truck

During lunch I picked up one of the new K-Line panel trucks (REA) at a local hobby shop. When I got back to the office and took it out, I noticed is has a sag, as though the frame was bent.

Anyone else have one of these and does it have a bent frame?

NO BOB mine is the UNION Pacific, one of the first ones out and runs great. No Sag.
