Smells good!!
I've never done ribs overnight. I'm stuck on the 3-2-1 method.
Nice Jeep 
If you can get your pit tuned - it is the way to go. This old NBBD was basically new when I found it a decade ago. I had the firebox welded on and I had Horizon Smokers make a charcoal basket, a heat dissipation plate and the chimney that is welded on the right side. Added a couple American made Tell-Tru thermometers and it will hold steady at 215-240 degrees for four to six hours depending on how strong the wind is and how much I have to open the air intake. Wind seems to have more effect than cold on burn rate needed to keep temps where they need to be. I gave up on welding blankets a while back and just fight it out now, but am thinking about building a three sided enclosure or maybe just a portable screen to keep the wind off.
I sure wish that New Braunfels had not sold out - the Black Diamond was the very best of the ECOS (El-Cheapo Offset Smokers). It was made of heavy enough gauge steel to make it a good performer, but it is still much more portable than a Horizon or Klose pit.
I am not a fan of pellet grills & smokers.
