Climbing/Descending steep grades - 2wd...
I've got a base model '06 e250 w the 5.4l and 3.73 gearing and a penthouse seating for four w a rear face to face bench. My family enjoys exploring lots of fire service roads for dry camping and good vistas in the PNW, some are invariably steep but don't require 4x4; if anything a posi-locker can get the job done.
I'm wondering if anyone has a good solution for dealing w steep grades a 2wd, both going up and down. 1st gear w 3.73 gears just doesn't provide a lot of engine braking... not to mention petrol vrs a diesel.
Install a Transfer Case but no front axle?
One idea I had was to look at installing a transfer case but not the front axle equipment. Thought being to just have the 4Lo option of the transfer case. Not sure if this is much more economical, but figure it's gotta have some significant savings. Not having the fwd axle would save from lift requirements?
Someone on another forum suggested a 2speed rear axle, but I can't seem to find much options for that for a 3/4 truck platform... most are for dump truck / semi tractors.
Looking for some constructive criticism or pointers, open to any good directions to explore to help.
