The hogs have hit Texas pretty hard. The meat can be a little dry. I inject with my usual plus a stick of melted butter (I have also used bacon grease and experimented with a few other oils like garlic infused canola), dry rub and then a mustard slather. Keep the water pan full with boiling water. Prepare to mop when checking the water or anytime the door is open.
Smoke low, low, low and slow; 200 to 205 is my go to on this meat. Don't give the meat a chance to steam. To reiterate Tenpoint's wise comments; check it early. It may be ready to give it up at 180 degrees. The usual 195 probably means a dry product. When the meat is barley fork tender; Foil, Towel, Cooler to give this a final chance to finish throughout.
Good luck and slow smoking,
