I recently changed the bunk boards on my pontoon and chose not to skip the bunk carpet as I think that it is extremely over priced. I went with treated lumber and have read that treated can effect the aluminum on the pontoons if kept in contact. After a lot of research I chose Ironwood's EZ slide due to the good reviews and design of their product. I lined my trailer with slides at the distance they suggested and it works beautifully. The first time I loaded my toon I cut the engine and walked to the front of the boat to latch the winch strap and my boat slid back into the water from the weight shift. I never dreamed that they would work that good.
