what did i do wrong with my butt?

Sounds like nothing! Maybe only go to 195F internal temp next time. Still, five degrees shouldn't make that much difference. Sometimes it's the meat, but that's not usually the case with pork. I just pulled a shoulder cooked to 200F also. Thought it was a little dry but only a spot or two, rest is ok. Maybe you got that (lean) spot? Forunately there's sauce!

Are you eating it cold or cool? All the gelatin sets up when cool, and any leftover fat congeals. Will not seem moist, or very tender.

Pulled pork must be gently re-heated. There should not be much moisture left, but lots of gel that when warm enough to be liquid will give a succulent mouth feel.  Folks often add some cola, or some generic sauce for the re-heat.

you let it cool.

remember that you basically drive all the conventional moisture ('juiciness') out of it by taking it WAY past the temps you would allow a regular roast to reach.  if you had taken it off at 140, for example, it would be plenty juicy.  but it would also have been plenty tough.

the strategy with PP is to cook it so long that the stuff which makes it tough (collagen), breaks down.  unfortunately, at these temps, most moisture from water (which is what a roast's juiciness really is) has been driven off.  or, when it is opened up, evaporates quickly when exposed to the air and being 200 degrees.

thankfully, the collagen not only breaks down making the meat tendr, but it literally becomes gelatin.  and that melted gelatin's slipperiness and succulence is what replaces the long-gone water.

but if allowed to cool, the gelatin solidifies (just as Jell-O does).  this binds the meat back together, and is also no longer 'wet' in feel.

problems arise when you reheat.  reheating to the point where the gelatin melts takes energy.  that reheating helps to drive any further remaing moisture (water) away.  reheating more than a few times, and you are in trouble.

if you ate it cold (it sounds like you did, but i'd be surprised if you didn't reheat), it would not have any melted gelatin, and would be very dry.

if you did reheat, you'd have some gelatin, but less moisture than if you just ate it while hot.

no reason to rest PP, or allow it to cool.  it's best eaten right then and there.

when i reheat it, i use the microwave (for small batches).  it's quick.

if i have a tray of it, i will keep it in a foil tray covered in foil, and will sometimes add some liquid.  but it is always best fresh from the egg.  let it trest an hour or so, not for juiciness's sake, but just so it isn't so hot when you shred it

I'm sorry but after reading the brisket story above the obvious answer is you weren't drunk enough

That was a mess. Had to share.

Ya' know, this is gonna sound like cheating, but I smoke my butts for about 4-6 hours, and THEN pop 'em in the crock pot over night in about an inch of apple juice if I'm gonna pull it.  Wanna talk about tender and juicy?   Try that little trick. 

it did work perfectly.  the egg had no idea the pork was gonna go into the fridge
)

Did you have a drip pan with some sort of liquid in it?  If not, that might help

i will try that.  i have cooked one in the crock pot and it turned out great.  I almost dont want to because when i spend a poop load of money on a cooker i expect it to work perfect but i need to remember the learning curve.. ive only had it 2 weeks lol

Thanks for everyones help

stike explaine what happened. If you have a vacuum sealer bag the pulled pork and reheat in simmering water for a good long while. PP isn't the best served cold

Ok. I just did my first one and it actually came out great. The end was a tad dry but it got rave reviews from my wife and kids. I cooked mine at 250, for the most part, but at some times it got a bit higher (270ish) bc I mistakenly let the fire get away from me and I think I used too much charcoal. I did a 5.5 lb pork butt that I got from my butcher which had lots of fat on one side. I cooked it fat side up directly on grill with an aluminum pan on top of the platesetter with a little water as a drip pan. Started it about 5:45 am this morn and it hit 195 about 4:45-5:00 pm. Wrapped it in foil for about 15 minutes until the reat of din was ready, then pulled it and ate it warm. It was delish. From what I have learned from the forum I think u might have been better off wrapping it in foil and a towel and putting it in cooler rather than fridge. I m told it will stay warm for about 5 hrs that way. Next time try cooking it at 250-260, fat side up, and take it off the grill at 195 IT. But like others have said, it was prob the meat itself as well. Hope that helps.

Rblument: don't worry about the amount of charcoal.  there's no effect on the temp, it's the size of the FIRE which determines the temp, and the size of the fire is determined by the vents, not the amount of available fuel.  just as your car does not go faster with a full tank, the egg will not be hotter because it is full

in general, it's the cooling and reheating that causes dryness.  it really is best eaten straight off the egg, but if you need to hold it a few hours, you can go a long while by putting it in a cooler and allowing it to sit, insulated.  it'll still be hot after 5 hours or more
