2 or 4 wheel drive? The owner's manual on my truck covers recreational towing. You might check the owner's manual on the candidate 2006 truck - the 2nd generation Dodge 4x4 trucks could be towed 4 down with the transfer case in neutral.
If it's a 2 wheel drive, you'll probably have to check with Remco for a driveshaft disconnect.
