I have an 03 and love it. My 10K Artic Fox 5th gives it a run for its money even with a Smarty set at tow mode. I was thinking of going with a 2015 but want to know the diff between the 2014 and 15 as you understand it. Is this a good time or is a new model year coming soon? I love air ride suspension but the 3500 dosent have it? and.....I really want the Asin (? sp) transmission with the higher output motor and is that only offered in the 3500 as well. That would mean trade perhaps a more versatile suspension for the motor/transmission
