Featherlites around here almost exclusively, probably due to dealer availability. All aluminums for everyone, for cattle. Rivets last longer than welds, but come "loose" quicker. Just get to know the dealer (or an aluminum welder) and get the welds redone immediately when they break. Overall, it lasts much longer that way.
If you're using it for cattle, you will not be able to load a 3-bay short trailer anyway, as the critters hit the front and then immediately turn to come back. Especially with bulls, it's a great way to get yourself knocked cold and run over as they come back out and you're trying to push the bay-door closed. Never let a new 'hired hand' do it. With a 32' trailer, we still only run two bays.
