I think your estimate is pretty good. My Ranger has a 7 ft bed and extra payload package, and I can stack the logs up pretty high if I want to. But the weight is the real limitation. Having broken a rear axle before from overloading, I do stop at about 1/3 cord per load.Some Like It Hot said:1990 Ford Ranger, extended cab, 208,000+ miles, 3.0L 6 cyl... We figure we get about 1/4 of a cord per load... I see others estimate 1/3 cord per load in their Ranger, hard to say. Rangers come with several different bed lengths.
BTW, I'm 6'5" and fit in the regular cab fine with the seat back all the way.
We joke about getting a dump truck, sometimes we make 3 trips in one day to a wood source. We get 20+ MPG with our truck, and are trying to avoid the 4WDs for the next purchase since their mileage is so much lower than the 2WDs.
Boy I can relate to that... I'm keeping an eye out for a basic trailer. If I could get another 1/4 cord per trip that would be very worthwhile.
