how bad does your gas mileage drop from an regular cab to an extended cab?

[jth2012]

same vehicle, same engine, same everything, just wondering how bad of an drop it would be, for a small truck, s10, ford ranger, type of vehicle

also a side question when did abs come into s10s or ford rangers?

[Debonair]

not that much. I have an extended cab V6 and i'm getting better mileage than people with standard or extended cabs. One guy with a crew cab S10 is close to my numbers

i thought ext. cabs had better aero than reg, so maybe its a wash with the extra weight.

I also have an extended cab and am getting much better FE than most with or without an extended cab. I also find that I get better fuel economy with a topper on it than with an open bed (true on all three trucks I've had).

I find regular cab trucks to be nearly useless, I dont even consider them when looking.
I would use the rear seats to hold a few tool boxes and stuff I dont want to leave in the bed and still have room for more than 2 more people.
