I can get a dual axle 2006 model 24' cow trailer, or a tri axle 28' cow trailer it's a 2014 model. Only $1500 difference. I'm leaning to the 28'. Never had a tri axle. Any down side to the extra axle, other than 2 more tires to keep in service? I have "heard" the extra axle draws more attention from the DOT.
