I agree with Graybeard
I have 12 tower stand and 2 tree stands, with PT all the way, even the ladders. The oldest is a tree stand, that is 10 years old. The stand is still excellent condition, but the tree is unsafe, its about to die and fall. Two of the ladder rungs, need to be replaced, and thats all.
I have 12 wooden all Pressure Treated, tower stands, from 12ft and some at 16 ft. Oldest 4 years and still very strong.
Here in Oklahoma, we have insects, humidity, and lots of hot sun. So, yes I keep an eye on my stands to see how they are fairing, and so far, they are doing fine.
Now the price of the lumber has gone up so much, that I can now buy a factory built tripod stand cheaper now than building a wooden one. That is depending on the size of the stand. Some of my stands, have a 4ft floor plan, and some have a 5ft floor plan.
