Quick question...I live near Savannah, GA and we fish a brackish river half of the year. Depending on the ramp we sometimes see some pretty salty water. Years ago my very first bass boat trailer rusted out in 3 years even with regular flushing. Now that was before road armor and all of the other coatings they have today. Every boat I have owned since has had a channel frame trailer. My question is, are the newer tube trailers that much better than they were in the past? I am looking at getting a new(er) boat and many boats that I really like have the tube and I am just hesitant to pull the trigger on 35-45k for a boat with a trailer I might have to replace in 5 years @ $5k. Thanks for any feedback.
