I'm sure that there are many who have done this, but, the manufacturers
don't supply stainless for the tower leg joints. As inexpensive as a bolt
kit for Rohn 25 is, I can replace them in 20 - 25 years. If yours aren't
lasting as long as you would like then maybe you need an Engineer to assess
your situation. Stainless frequently requires special handling, i.e.
Anti-seize and strict torque specs.
