Welcome to the forum.
Tom hit the nail on the head for pork chops. Pork loins (bone-in or boneless) will work in your smoker. I recommend a 3-5 lb loin roast.
Brine the meat 3-6 hrs with:
12 oz apple juice
1/2 c sugar (white or brown)
1/4 c kosher salt
2 tbsp Worcestershire sauce
Pat dry and smoke at 275o until center reads 135-140 o (140-145 o if you prefer non-pinkish pork) Let it rest a bit before slicing.
Apple or cherry wood work great with pork...Hickory if you prefer a more pronounced smoke flavor.
I've got one of these baby's ready to go into the pellet pooper in a few hrs. Can't wait

P.S. The 275o smoker temp helps promote caramelization and a little bark on the roast. As Tom says...hot & fast works better than low & slow when cooking pork.
