Place quartered potatoes in the bottom of the slow cooker and place meat on the potatoes.
In a separate bowl whisk together soup, cream cheese, and dressing mix. Spoon over meat and potatoes in slow cooker.
Cover and cook on low temperature setting for 7 to 9 hours or on high temperature setting for 4 hours.
Use the extra sauce as a gravy for the meat and potatoes.
Notes
To keep from the pork roast from drying out, it's best to cook pork on low. The high heat can cook similar to boiling, where the low setting on your slow cooker will be more of a braise. Just watch it toward the end of cooking time so you don't overcook it. Pork shoulder roasts will self baste and stay moist.
