if you want to see just watch an aluminum trailer with a boat going down the highway, watch it flex and then watch a steel one. 1 thing i didn't like about the aluminum ones i've had they will float without a boat at the ramps due to the tires an air under the fenders, then you run the keel into the trailer and hope the trailer goes down without hurting the boat. both will rot just wash the trailer after being in salt as you do the boat. the aluminum trailer will corrode away around the stainless bolts then they pull threw the trailer frame. one reason you see alot of aluminum trailers with hugh fender washers fixing where they have either cracked or corroded away around the bolts. and remember no matter what you buy the axles all have steel spindles and hubs, and steel springs unless torsion then it has spring steel inside the torsion axle, so really no difference in the axle area. plus don't forget what happens to your lower units after salt use they get brittle as so will that trailer even faster since they aren't painted.
