Yes CW, saltwater boats require a bit more maintenance. I just put 5 new Carlisle HD's on my 4 year old boat trailer. It gets washed down after every trip, either at the car wash or more likely in my driveway with my pressure washer. I hit it with the leftover Salt Away after I use that in the outboard. I open all storage doors and let it sit out in the sun to dry before storing in the garage. So far no issues.
I sometimes tow it 2 hours on interstates and I really don't want to be on the side of I-10 before dawn changing a tire.
