2018-19 Nexus Viper Class C

Phil, you and I have knocked this topic around for years... If a 450 weighs several thousand pounds more than a 350 and that is the case with the later models, and they both have the same motor and trans the 350 does not have to work as hard. Add in the differentials {4:10 vs 4:56} and the difference in fuel economy is easy to see.


We agree there isn't all that much difference between the 350/450 except the GVWR/GCWR which is currently a ton. Yours and mine {2005/2011} have slightly different numbers.
