Sorry. I've never had a problem, and I get significantly better fuel mileage than a buddy with a 2012 non DEF truck gets. In 25K miles, I've only filled up maybe 5 or 6 times total. Hardly big deal and rarely any trouble at all to me...
It is way better than the 2012 setup. After all, we have to use our Rams as urban air scrubbers to satisfy the ultra greenies who got congress to pass legislation forcing emissions down to almost impossible levels. My 2013 gives all zeros, and opacity lower than ambient air, so it cleans up Henderson air when I drive. I refill my blue def plastic 2.5 gallon jugs at truck stops, and have not had trouble with them.
Maybe I'm doing something wrong when I attach it.
I just fill at the truck pumps at fly J..........easy as pie.
The SCR requires more maintenance, yes, but it has also improved the overall reliability and efficiency of these trucks.
I wait until I get the DEF low warning, fill with 2 jugs and go on. Never had an overfill situation, very few times have I ever had a drip, and never any spillage.
