I think everyone knows I am a RAM/CUMMINS guy but there is no way that truck got 14mpg on such a short run. Maybe run 300 miles the 14 would be possible. The Lie O Meter is more accurate under this condition.

This fill two click is a joke! Fill the SOB to the top until fuel starts running out that is the only way the test can be fair. Also same pump matters also, at least they did that.

I agree the capless fill is a joke! I will be getting a cap from Geno's for mine.

Kent get that missing tooth fixed!

This is a sham of a mileage test! :S There is no way to get an accurate reading with a pump refill even from the same pump!! Then run at least 300 miles! Ten check the mileage.
Yes, another RAM/Cummins guy saying sham.

Easy to fill to the top of a 2nd gen RAM as you know. I alway do that and get accurate MPG every tank. On the 11 it was harder but possible this one sucks because if you retract the nozzle to let the bubbles vent and look to see the fuel filling the second flapper closed inside the fill tube and then fuel spills out!

So I may investigate removing the second flapper.

Bottom line the test was a farce. I would trust the lie O meter well before the two click method.

Some day I would love to tow the same road with another RVer from fill to fill to compare my 4:10's to RAM's 3:73's. I believe the 4:10's will get better mileage at my weight level of nearly 30K combined.
