People overlook their trailer and the maintenance of the trailer. We put more miles on our trailer than we do the boats. I bought a lowe catfish 20 alum. last year and it came on an aluminum trailer with torsion axle. If i had to get a different trailer it would be tandem but the torsion axle just floats the boat going down the road. I hand pack my bearings once a year, guess im old school.... thanks for the thread.
