Looks like the truck liked to get out and stretch its legs on the Interstate. Looks like Jan2016 fill was 28.29mpg, was it the axle swap or the short commute? Looks like a slow taper off on FE is the motor unhappy, pluged cat, spark plugs got my life time best non airo or with the cap first run @55mph for a full run @27.7 in a 3/4 ton dodge. 8/100 mi p&g+55 is a huge boost.

If the short 7mi route is the killer in your mpg ,then grab the paddles and give it som grid juce. Add block heaters or 2, trans , dif and oil pan.
Gumby stay flexible
