Ok, all of these topics are good info.
1. Get a box that works.
2. Marinades / brines
3. Wet vs Dry, seasonings and rubs vs wet mops.
4. keeping moist meat....
5. Heat, and maintaining heat
6. How long do you cook the damn thing?
1. I didnt spend a 1500 on a ceramic Egg or something. I went with a side box, vertical.
I got it a dyna-glo, on sale at amazon, side box, for like $180. I can cook 2 full turkeys, 8 chickens, 5 full sides of ribs, 4 briskets, or some combinations of those.

2. I brine, longer than recommended, and then fridge marinate for a couple of hours.
3. I smoke with water (will explain later) so I do dry rubs. I wipe the liquid of the marinade off, and then dry rub with the seasonings I want. I always score a bit and add brown sugar as about 1/2 of my rub, but i use strong spice rubs.
4. Since I cook with dry rubs, I put each meat in a cheap aluminum pan, and flip it every 4 hours. At the bottom of the smoker, I put a deep pan of water, with a whole chopped onion and ~8 cloves of garlic. I add water about every 2-3 hours. This keeps my "smoke" about 1/2 steam, and provides a ton of moisture, to keep from drying out the meat.
5. Some people do complicated firebox mods to their smokers to make them run longer, snake, etc. I epoxy'ed a fireproof thermal blanket over my firebox to keep the heat in the box (I have enough to do another if you want it), and I check it about every 2 hours. I do a combo of Hardwood charcoal, hardwood/oak, regular briquet charcoal, and flavored wood (wetted, in a box, inside the smoker). I try to keep it about 35% hardwood charcoal, 15% hardwood, and 50% regular charcoal. I burn the regular charcoal to white coals in a can before I add it. I could run more hardwood charcoal or actual hardwood, but that takes the heat too high. So, to keep the heat low and slow, I keep those percentages.
Pre-burning the charcoal in a Weber can keeps my heat very even at about 210, and my smoke nice and clear. If you have white smoke pouring out the top, your bbq will look like the original posters pic, some bark, heavy pink ring,
center white/brown, and be really bitter to the taste. You want light, wispy smoke coming out of the top of your smoker.
6. It all depends on how much heat and how clean your smoke is. The lower the heat, with clean smoke, it should go longer.
Beef ribs, I like to do about 5.5 hours. Fatty pork ribs can go about 6.5-7. Brisket depends on which cut, how thick, and how much burnt ends you want, as well as how you trim it. 6-8 hours depending. Pork shoulder, I like to run for about 9 hours. I also add some Dr. pepper to it every time I flip it.
My dry rub with a wet/steam smoker trick seems to keep the moisture in the meat much better, so it can go for longer. If you keep the heat to 215, which I consider just the perfect temp, then you can cook for longer. If you run at 230, you need to cut your cooking times.
The last party I had, one of the guys was shaking the pork ribs. His comment was, I have never seen meat just fall off the bone. He gave the pork ribs one shake, and the meat fell off onto the plate. Not saying I make the perfect ribs, but they are damn good.
