Next time you might want to try putting the water pan above the fire with the bricks as support/spacing.
What temp did you achieve with the smoker?
I use the minion method, load however much into the firebox with a coffee can-both ends cut out- in the center. Use a chimney to start the coals -roughly 16- and put them lit into the can with a set of cheap tongs. Pull out the can and the coals will start the ones they touch and spread as they burn. I can get nearly 14 hours at 250-275 with the UDS and 250-300 out of the ecb for about 8 hours.
The early bird may get the worm, but the second mouse gets the cheese.
