That's hard to say; definitely over 10,000 lb, and somewhere between there
and 20,000 lb depending on a lot of factors.

Actually I think '88 is when the Navistar engine went from 6.9L up to
7.3L. The Powerstroke didn't happen until '94 or so. Between then there
was a "pseudo-Powerstroke" which was a non-turbo version, but it was only
offered until the Powerstroke came up.

Right; I don't think Ford made the Crew Cab available in the F250 line.

I think all F350's came with full floating rear axles; the front was either
a live axle for 4WD or twin I beam for 2WD. I'm not sure what is meant by
HD, but it's probably Heavy Duty.

Actually, the duallie option will lower the towing capacity, by the weight
of the extra wheels. And duallies weren't available with 4WD anyway.

Well, there was a period of about 2 years when a non-turbo "Powerstroke"
was available, but once Navistar released the real thing, that's all
that was available. For the '99 models, they're adding an aftercooler.
Cavitation doesn't need to be a nightmare. If the owner did his job
right and kept the wetting agent in the coolant, then cavitation erosion
won't be a problem. To check for that, you can get test materials from
Navistar which are similar to litmus paper. So long as the concentration
of wetting agent is correct, then there shouldn't be a problem.

The towing package I think is just the wiring pigtails. The F350 already
has the big cooling system and stuff. Someone more knowledgeable will
be able to jump in here.

There is a limit to the amount of power that a limited slip diff. can move
over to the wheel with the greatest traction. I can't remeber what it is but
it is different from the posi-track units. The detroit locker is niether, it
mechanically connects the wheels like a spool so that one wheel can't turn
without the other. It will only disconnect a wheel when going around a
corner, when the outside wheel takes the longer path and spins faster than
the inner wheel. The over-running wheel unlocks from the drive train and
makes a clicking noise untill the inner wheel catches up with it.
Here is the problem, when coming out of a turn the outer wheel is still
unlocked, when power is applied it only goes to the inner wheel and the
vehicle will pull to the outside untill the over-running wheel locks back in,
sometime violently. This undesireable "steering" effect is more pronounced
in a short wheel base truck. I had to take it out of my full size Bronco
because I felt it was too dangerous.
Lockers are also sensitive to tire diameter and to set them up properly you
forget about tire pressure. You air them up using a yard stick to measure
their diameter. Unequal tire diameters will fool the diff into believing it
is in a turn and will be partially unlocked all the time. This will be more
troublesome in a vehicle with a stick shift. It might steer to the ditch
everytime you up or down shift.
Lockers are best off road and if you want to ride around town, stick to a
long wheel base truckEnd of fordtrucks80up-digest V1
