Well, I tried the socket extension in the drain tube and I could not get it to straighten out. When I would push down it would push up on the floor inside the smoker. I finally received an email back from Masterbuilt and they said it did not appear to be bent enough to cause a problem and if I wanted it fixed I would have to return it to the retailer for a replacement smoker.
Last weekend I did 2 racks of baby-backs and 2 racks of spare ribs. This produced enough drippings the drain was needed. Unfortunately since the tube was sloped up it did not "drip" into the drip pan. It rolled down the underside of the tube and down the back of the smoker right onto my deck. I know have a really nice smelling stain on the deck. I guess Masterbuilt was wrong.
I ended up returning it to Cableas. My new smoker is seasoned and waiting for the first smoke.
Thanks to all for your input.
