Even with New Injectors

Even with new injectors installed I am only getting 9mpg pulling my 32ft 5th wheel. It grosses out around 12k. New K&N air filter, Smarty Jr. (in tow mode), new fuel filters.

any other ideas

put your smarty in economy mode if you want fuel economy. adding more fueling/power isn't going to net better fuel economy.

what is your gearing and tire size?

How much frontal area on that 5ver? How fast are you towing it? I got 12.5 mpg over about 4800 miles in my 08 (and again in my 12 valve) towing roughly that much (+/- 2k or so) in a bumper pull car hauler.

yeah, speed and wind drag will also play a big role...

the faster you drive, the worse your economy will be.
