No, its not a 48. It is a 36" by 15" propane tank I crafted into a mini Lang look a like. I used to have small firebox attached to it and it was mounted in parallel with the 60. I mainly used it as a warmer but it was also a great little charcoal steak grill. My firebox wasn't big enough for good control of high temps, so I cut it off and have relocated the BABY so I can use only one source of fuel.
Dan, Are you planning a road trip with a 2" ball trailer hitch soon??
Cman95, to answer your question about the vent control, Yes, if you look closely at the pics, you will see a sliding vent that can be fully closed or open and anywhere in between. At full closed, no smoke, the baby stays at 200, if I add water, it can go less for warming. At full open, with smoke, I can only achieve 325, so I am going to drill 2 more holes in between the others(already prepunched them, but wanted to test 3 holes first) I will keep the thread posted as to whether I fail or succeed:-)
Feel free to add ideas or warnings. I am concerned about tinkering too much with the firebox but I am thinking that multiple round holes is more structural than one big hole which could cause cracking.
