-I don't peel the potatoes before boiling. Peel after the potatoes are cooked. I always leave some of the peel attached.-I used regular sour cream. Low fat sour cream will also work in this dish.-After the initial mixing of the sour cream and mayo with the potatoes, the potatoes will absorb some of the moisture. I always add a bit more either sour cream or mayo before serving. Wait to place the final garnish on the salad until just before serving.-I use French's brand Spicy Brown Mustard.-If you really want to truly mimic the flavor of a loaded baked potato, add some grated cheese as well. I would only do this as a garnish to the top of the salad so the cheese doesn't get soggy.
