Welcome, Randy! I would agree with others that a #3 sounds like a good choice for you. I have a family of 4 and occasionally smoke for 6-8 people with my #2. I can get 3 or 4 racks of babybacks in the #2, and I have done a couple of 5# chickens, or 25 or so wings at one time. If you want to smoke more meat at any given time, then the #3 should accommodate you well.
Happy smok'in!
