DW and I are dreaming of a step up in trailer size. She retires in a year
and so we're looking at 5th wheels.
Bought a 2007 2500HD Silverado alison/duramax turbo with 72,000 on it.
We immediately hitched up (like the next day) and towed our little
7 1/2 foot wide 4200 LB ultra lite to Florida and back to KY.
Total trip right at 2000 miles.
We kept track of every gallon of fuel and mile.
Over the entire trip I averaged a dismal 10.5 MPG
I know the Ford guys and the Dodge guys will also chime in but I'm
trying to compare apples to apples.
Chevy duramax guys-- what is your honest MPG??
If you have made modifications- what were they and how much did
they improve your MPG?
I'm not in love with this truck-- it's a work truck so doesn't have as many
of the creature comforts as my 04 1500.
I may just sell it and stay with my current rig. (Current truck has 44,000
and garage kept and looks NEW.)
We are struggling to decide if we keep what we've got--
see my signature- or keep the diesel and maybe move on up trailer wise.
What are your real life MPG figures??
