I have a 16ft trampoline, about 3 years old in great condition. Barely used. Springs are clean. It has tall safety nets with no gap design that connect on the outer perimeter (gives more interior space).
I have it strapped to 4 anchors and it has never lifted in high wind storms. I have 3 new heavy duty anchors that I was going to use to add to or replace the original anchors, but have not needed to. They will go with you as well.
to review more specs, it's this one on amazon: https://www.amazon.com/dp/B09FPXM84T?psc=1
already disassembled and ready to load up. easy to put together, can walk you through it.
