Posi vs 4X4
I know this is the towing board, but this question does relate to towing. I presently have a '87 CC 4X4 w/460 5 speed, 3.55 gears, single axle. I tow reciver hitch trailers up to about 7000 lbs. I sometimes also have a ton or a little more in the bed. I don't have a gooseneck hitch as of yet. I am considering buying a good used '87 CC with a 4.11 posi dually to do my towing with and use the truck I have now for a carpentry truck and light towing. I'm concerned that I'll miss the times when the 4X4 comes in handy, like when a couple inches are on the ground and the snowplow hasn't gone yet. I also like the low range of the transfer case for backing around and the 4 wheel drive for times in slippery surfaces or on hills. I'm wondering what other pullers and towers think of 4X4 vs posi in terms of traction and getting stuck or 'unstuck'.
thanks,
Tony

The dually setup may make the difference, but I have no experience there.
I have a 94 F250 4x4 with limited slip/posi, not a dually. 99% of the time 2x4 does fine, but on those rare occasions, usually a couple times a year, having the 4x4 and low really gets my butt out of a sling. Especially helpful when towing a load and getting stuck.
BTW sounds like the load you are putting on the rear may be a bit much. Check your GAWR ratings and if you get a chance, put your truck on a scale. A ton in the bed plus a trailer is probably too much for safety and wear and tear.
Good Luck,

Tony,
Be aware that your licensed weight only satisfies the DOT, Highway Patrol doesn't care about your license, they care about the manufacturer's ratings. If you're over weight, some states make you park it until you can get someone out there who can legally tow it for you. Just some food for thought

Posi on a duelly? I love posi but it can be abused. Even on a normal axle it takes a tough rear end to handle the cornering in normal driving. On a duelly it must be even worse. The clutches in the axle would get a good workout. A 4x4 duelly I think is the way to go. I know of a few guys that thought that posi was the solution for towing on a 2wd truck. A 3/4 with a heavy front end (diesel) and a 2WD posi. They bought a 3/4 4X4 duelly in less then 6 months.
