I have 3:55's, I think for a some time tower I would say they are the best, as far as get up and go I can smoke a comparible 4:10 truck empty since I can stay in the turbo and subsequently power band longer. I would say anthing lower that that would be absolute overkill, stock I could get over 21 on the highway if I babied it, I know average about 16 or 17, but a gasser with my power would probably get 7 to 8, or less.

As far as towing, the biggest load of towed with it was 10-12k, and it had NO problem with it, and still got good mileage.

I still don't use first a whole lot, it is geared very low intentanally to get heavy loads moving, so unloaded you probably won't use it much, I only do taking off on hills, or wet ground. Have to slip clutch too much on hills, and on wet roads taking off in 2nd it is VERY easy to obliterate rear tires...

I know they are expensive, but an overdrive unit would be the ticket, then you would have best of both worlds, towing power, or mileage power. If you have too high gears behind a stroke you will only burn more fuel cause you will have to keep it spooled to maintain speed.
