Just picked up my 03 last week, how can I tell what axle ratio I have? I see from the dodge towing guide that the 3.55 is rated for 7550 and the 3.92 is rated for 8550. This could mean the difference in terms of which camper I can pull (picking one up next week). I have the towing package, so all I need now is to put in a trailer brake.

 

Nevermind, found the sticker in the glove compartment. I have a 3.55 axle ratio.
