one thing I don't like on the newer diesels, 07 and newer is that darn filter you have to mess with. they get clogged up and you either have to replace them and or have them cleaned, neither is a cheap maintenance thing.
I've never had to "mess with", "replace" or "clean" the "darn filter"
I have 32k miles on my truck.
Empty highway mpg running no faster than 65 mph I get 16-16.5 mpg.
With the camper I get about 12.5.
A friend once posted a message that said "if someone is worried about what MPG their truck gets with an RV on it due to increased cost to drive it, then they shouldn't be owning an RV."
