I will probably some day own an EV for local personal transportation. But not for towing, Especially not for the kind of cross country distances I tow.
I have had a Ford F-350 SuperDuty with single rear wheels with the 7.3L Goliath gas motor, 10 speed transmission and .430 ratio rear
axle, on order since the first week in February. I could have had it sooner but I insisted on the gooseneck / fifth wheel tow prep package.
Admittedly that would be a bit much for a
Scamp or
Casita but it would be just right for a 25'
Bigfoot. And I can certainly pull a
light weight trailer. Just have to keep checking the mirror to make sure it is still back there. I have heavy duty tilt bed flatbed trailer that can weigh as much as 20,000 lbs loaded that I use on the farm. I am out of the diesel engine market because of the emissions control problems and the expense.
I ordered the camper prep package (which includes a stabilizer bar on the rear
axle. And I ordered the snow plow prep front suspension which includes a stabilized front
axle. The total GCWR is 27,500 Lbs. I want to make sure the trailer can't push the truck around. I like the safety, stability and feeling of "road command" that suspension setup provides.
I expect the highway gas mileage will be around 14 mpg not towing. It will be around 8 mpg towing a 7,500 lb RV trailer. Less or more depending on the wind direction and driving speed. On the flat level interstates I set my cruise control at a maximum of 67.
My '17 model F-350 had the same suspension, but a weaker 6.2L engine, six speed and .370 ratio rear axle. It worked pretty well pulling the 25'
Bigfoot (weight about 7,500 Lbs) except when running in the mountains. The weak link in that setup was the six speed automatic transmission. It was great when not towing but it would drive you nuts towing a heavy trailer. You had to go to "M" and manually shift to keep the engine running at a reasonable RPM (between 2,500 and 4,100)
I need the new truck strictly for towing. I have a
light weight 12 year old Ford Ranger that I use for errands and when I am not towing or hauling anything.
