Hi guys
New here, love the forum so far.
I recently bought an '06 Chev Crew 1 ton SRW LB 4x4 LBZ. My first hand calculation of mileage running empty at average 70mph was 18.32 US MPG. My next was a long trip pulling my 26 foot holiday trailer (which my wife likes to load to the nuts) again at average 70 mph and I hand calculated 10.41 US MPG. Not quite as good as my old '93 Dodge Cummins, but then she couldn't pull that rig at 70 mph all the way, either. I am a mileage buff, too, so I will likely post more results as time passes. With fuel prices skyrocketing lately, good mileage is a big concern. I think a 2 mpg increase would be worth it to justify a "mod".
