Well I dorve 18 hours over the weekend to pick this up. It was on Craigslist advertised as an Attack DP 45. Well come to find out it is a DPX (with fire tubes and turbulators) New never fired! Had to use the backhoe to unload this 1,100 pound beast. Well I'm installing it ASAP this thing is a great looking boiler. Thanks for all of the advice. I'll be posting install pics soon.
