If I were to trade in my 4Runner for a new one, I'd go back to manual,
even
if I had to buy a different breed. I like being able to shift when I
want
to. I don't like the auto dropping into another gear any time it starts
climbing a hill, while towing. Using the cruise control, with an
automatic,
while towing is a waste. The damn thing is shifting continuously, so
cruise
control can't be used.

Yup, manual is the way to go.


Does the 4Runner have a "tow/haul" mode?

Virtually all the US manufactured trucks have it, including even the
little Ranger I had.
The auto transmission in tow/haul mode will do a much better job of
selecting the proper gear for the load than a manual transmission. Plus,
you have the benefit of the torque converter which will unlock under
load.
An added benefit, is that they change the gear shift points, reducing the
potential of lugging the engine and causing serious damage. Finally,
they also provide downshifts to provide engine braking while towing,
saving your brakes.

A properly equipped truck with an auto is much better .... in fact the
tow ratings are higher with an auto.

We just recently discussed this very topic. One of my vehicles has a
highly touted 6 speed computer controlled automatic transmission. I too
don't like the way it shifts while in cruise control in hilly terrain, so
I don't use it under those conditions. Otherwise I am happy letting the
transmission decide when to shift. I don't have the tow haul mode but I do
have selectable grade braking which is computer controlled. I'd be curious
to know what professional drivers think about these modern transmissions.

Your Allison is probably the best auto transmission made for heavy hauling,
heavy loads.
A professional driver would give his left nut to have one if they made it in
18 gears.
