My hunting buddy and I leave our ladderstands up year round. We occasiounally replace the ratchet straps, but never do anything besides that.
Same here. I found that I did as much damage to the stands hauling them around as I did leaving them up. I just finished a massive refurb effort. I took down the two oldest, cleaned off the surface rust, and repainted them. One was replaced with a new stand, and then both the old ones were redeployed to new locations. Those two will only be used as 1-man stands from here on out due to their age.
The other three will do until #3 son and I stop fitting in them together. My guess is that I have about 2-3 years to come up with a way to accommodate Angus and me in a raised stand before we start pushing the 500lb weight limit.
