I've been looking for two hours and I cannot figure out exactly which model this 209in ram is. Overall length- 2500 LWB Crew Cab: Regular Cab: 209.0 in (5,310 mm). Can anyone please let me know which model this is referring too. I want to buy this, but again, I can even begin my search BC I can't figure out the exact year (2009-present) and 2500 model of the one that is 209in. Thank you!
