I have never had any trouble TC. They have practically as many models/dimensions as you would want. One of the older ones they got for the weaned calf pen, it's verticals are closer together. All the rest I have are a little wider.
sstterry, they are high, but can't find a price list now. I thought I had one somewhere or a pic of one. It's been a few yrs since I bought the last ones. MFA has a truck that goes by the MFA plant/shop where they are made and delivers to Sedalia I believe. They then sent them on the regular route truck to a dealer close to me. Worked out pretty good. They didn't have any on the lot at the dealer.
All I've seen around here have been the Century's. Bars too far apart, and way more flimsy due to that I think. These things are solid, and took load straps to get put together, pia. I can't remember for sure if we had to redrill/wallow out any pre drilled holes. Wasn't many of them, if we did.
I think these models I have are the 52-24 and 52-18, iirc.
