Well hell Greg, that's because your's are relativly new.
---UPDATE--- OK, done as much as I'm gonna do on the truck bed. Damn sure not gonna get 100 bales on this rig--and that's just fine. A good dose of old motor oil gussy's er up just nice. Crap, I had a broke leaf on either side--I had to put hose clamps on them to remedy that problem. Hell, I figure that'll work till the clamps rust out.
Come on, they were heavy duty clamps.
