To other posters replies...... Sure the steel tanks rust. Not horrifically, but I toss them every 5-10 yrs and buy new. I never repaint them. Therefore, the three standard tanks I can buy for the price of one composite have a combined life span that seems a lot longer than a single composite.
Someone mentioned that their propane locker gets wet. That would be a deal killer, I'm sure.
In the PNW, everything gets wet, or maybe at best in a permanent state of dampness. I would think steel would be completely out here, although if painted a bit once a year it might be fine. The cost differential is huge. Worth a thought.
