Based on my research, the Dexter Trailer Hub and Drum Assembly # 8-201-5 will replace the 3160121 drums on your 2003 Airstream Classic. This assembly is designed for 5,200 pound axles and features a 6 on 5-1/2 inch bolt pattern. I have attached an article on how to measure your bolt pattern so you can ensure this will be the correct fit. The hub uses # 25580 inner bearing and # LM67048. I also recommend verifying the bearings on your existing hubs so you can be sure this is a perfect match. The numbers should be stamped onto the bearings themselves.

Then for compatible electric brake assemblies, you will use the Dexter 12 Inch # 23-106 for the Right Hand and # 23-105 for the Left Hand. These use a 5 bolt mounting flange pattern.

I have attached a couple of short video demonstrations on these products for you to check out.
