almost picked up a Ran 3500 today. looked at a lot. most had a 12,300 GVWR but the last one, it is the SLT also and it only shows as 11,700. why such a big gap. don't know what a 2015 3500 CC ...
Yes one must read the fine print, and get the correct truck if they want to tow a heavy fifth wheel. Pick that truck, and you will have very limited cargo rating compared to one with 12,000 pounds GVWR.
