Not bad at all! I used to think of buying one of the old trucks myself back when I drove for them. I assume you run without a CB in that thing, since there's no CB antenna. Yours also must have the seperate FM antenna on the driver's side since i see you have neither of the CB antennas - the one I posted has the FM radio antenna combined with the CB radio antennas.
If yours is an old Schneider truck, the one I posted is at least a year or two newer - they stopped ordering the sunroofs because they could never get them to stop leaking.
Also - if you really are after a trailer, when I left Schneider, they had something like a thousand WELL used orange van trailers sitting in their lot in Gary, Indiana.
