Question Flat towing 1986 F-250

Hi,

Before to buy this pickup, I would like know if it's possible to tow a F-250 (automatic, 4x4) behind an RV to travel around Canada/USA ? I read that I need to disconnect the driveshaft. Is there a product to do that quickly ? I found also a system at Remco I guess, but I don't know if it's works for this pickup.
Any other resources or product ?

Thanks a lot !

Looking at my service manual (1984 F250 Manual with Borg Warner 1345 transfer case) you need only put the transfer case in neutral. The rear drive shaft will turn the transfer case output shaft only. The Transfer case input shaft (and everything forward of that) is not turning. The transfer case output shaft drives an oil pump which will lubricate the transfer case the same as if you were driving it under its own engine power. You may have the BW1356 transfercase but it is similar. If you had a 2 wheel drive you can not flat tow ( just short distances at low speed).

Thanks Cyrusjohn !

How can I verify the model of the transfercase to be sure ? With the VIN?
And so, I don't need to disconnect the driveshaft ? Should I add the pump ? I saw at Remco that they sell a pump for that, I guess.. (sorry I don't know nothing about the mechanic ... ^^).

I don't know how to verify the transfer case you have other than looking at it. If you are not near the truck you are buying, and can't verify what transfer case it has, take the tools you will need to disconnect the drive shaft.

Ok I see. I can ask to the seller, maybe he knows the exact model.

And for the pump, it's the only thing I must to buy? no driveshaft disconnect ? If I understand your manual (I suppose that the 1984 model is close to the 1986..).

Personally, I would just disconnect the drive shaft at the rear diff. While putting the t-case in neutral can work, you'll still have multiple u-joints spinning, and if one fails at speed it really sucks. I only warn because I've had it happen before, but not while towing.

To disconnect the shaft it should just be 4 half inch nuts on the u-bolt things, and then it is free to be tied out of the way.

If it's just one or twice sometimes, OK, but if I want to use the pickup more often, this is very inconvenient each time to go under it. This is why I would like to know if the driveshaft disconnect can be installed on this model.
But as the repair manual of the 1984 model, it seems not necessary if I have understand correctly ? I'm pretty confuse..

if i tow an automatic trans vehicle or a 4X4 for more than 50 miles wheels on the road, the driveshaft is disconnected from the rear axle.
i have seen way too many towing companies eat the cost of new transfer cases and transmissions due to not disconnecting the driveshaft
