I see lots of claims of 170,000+ btu capacity, but it seems that it all depends on the PSI of the regulator. Soon I'll be getting a 170 gallon galvanized steel tank, and I'll be putting 2x high pressure burners underneath. I'm building the base from cinder blocks and insulating the whole thing. Any insight you guys might have on these things as far as most bang for buck propane wise :wink: would be great!
