Pilot Rock is better than Gametime or Miracle, heavier build, better welding. But, more costly. I prefer a concrete pad and bolts, versus the portable steel base, just a little more stable. You can prevent some rust with seasoning, but, they get dirty and disgusting (birds like to set on them) without a cover.
Out here in California, with moderate care, you see these units last 20 years, even near the coast, I have seen them go 10 to 15 with little problem.
me: I don't drink anymore
Yelonutz: me either, but, then again, I don't drink any less
