2low and manual lockup

Oops....right....4 low....sorry.:S

I have the Yukon kit on my 05, 2-Lo is a great option and I use it quite a bit when maneuvering with the trailer.

I also use a lockup kit, wait..er... I mean clutch :-)

ops...double posted

Yup...disconnect the control wire to the front diff. Break that control
wire with a dash mounted switch

Compound low is really cool for maneuvering...but...note that the
rear drive train is at risk if you get on it...and that the automatic
will NOT like it much with little to no air flow over the external
ATF cooler. Why some will cook their ATF backing up a trailer on a
steep driveway, or some such

Not enough time for me to do it on mine...yet

My K5 Blazer had put in a Dana 60 with manual hubs. Loved that setup
for low speed maneuvering towing a trailer on pavement. Never had to
give it much throttle and most times just idle was enough

Would love to have manual hubs on my Sub, but not with the OEM front
axle setup.

Manual hubs do need yearly maintenance and part of why the OEMs have
dumbed down by increasing the complexity of today's systems

Have used 2LO a couple of time when pulling stumps. Sometimes to get through really deep snow. Sometimes when backing my 5th wheel up a wet gravel hill and turning into a campsite. Sometimes it is just what is needed. I try not to use it much, except when necessary, because it spools up, binds the drive train, and is tough to get it to release.

I installed a front mounted cat3 hitch for the applications you brought up :)

I think you are talking about 4 low.
2 low would prevent the binding but probably not provide the traction you are looking for on wet inclines.

Can this be done on a 2006 Dodge 2500 4x4 manual tranny??

No, not cheaply anyway. You would need to do a free-spin hub kit, which converts the unit bearings on the front end to manual hubs. Currently, your front axle is always engaged (the front driveshaft always spins), and the only disconnect is the transfer case.

There is 2-3 different companies offering the kits for our trucks; Dynatrac, Spyntec, and I think Yukon. Cost is about $1800. Some guys are building their own by sourcing some stuff from a Ford Dana 60, but I don't remember the details on them.

2-LO is nice option to have...would be great especially when backing the TT uphill into a campsite at slow speeds. I always used 4LO on the beach but it binds up tight on hard pavement.
