If it's the original JT field with the fans, make sure all the fans and batteries work. We use some of the JT bunkers at our local field. They're pretty good but the wires for the fans tend to get yanked out if you don't snug the battery down tightly.
Also, check all the fan cowls - the little zipper things that hold the fans in place. Make sure they're all there and not messed up. The zippers tend to go after a while (once they're on, just leave the fans there when you take the field down; just take out the battery)
If everything is working, then two grand for this sounds pretty good.
