I've got a 16 foot dovetail dual axle with the wood plank flooring. It has about 6 or 7 years and probably 75-100k miles. How many years are you guys getting out of this type of trailer? It's starting to show some wear and the planks are starting to look worn. I've heard it is almost cheaper to buy a new trailer than to try to replace the planks. It's kind of a must need piece and want to replace before it crashes.
