Excellent thread. I was combing your posts after you posted your 1000-miles-per-tank thread to see what the truck spec was as well as relative climate and terrain. Wow, this is waaay beyond what I hoped to find.

I post frequently on CTD boards about FE, and what little interest there is is generally subsumed by "what magic box can I buy (that will painlessly increase my FE)?" The issues of climate & terrain have to factored just as much as truck specification (4WD versus 2WD, manual vs. auto trans, SRW vs DRW) before we ever get to, say, commercial vs. personal use and then finally to questions about driver skill (tire & brake life, for instance).

Just to establish a baseline for a possible comparison a whole buncha stuff has to be eliminated.

Maybe some aero will help. Maybe.

Rolling resistance issues alone (especially coupled to sloppy front end and steering components) are make-or-break on heavy pickup trucks.

So it's great to see clinmate/terrain being addressed. Now I have an idea of how to do it. Thanks!!
