First of all, what truck configuration do you have? Second, can you be more specific on you question? A 4x2 can tow just as well as a 4x4. that is of course comparing both trucks having the factory tow package. Some boat towers are concerned with the boat ramps being too slick and needing 4x4. Not much you can do with a 4x2 in that case. You may get an actual mechanical locker on the rear diff. but it will still be a 4x2.I was reading about the open differential and some other modifications that can be made for when we are towing larger size boats that are pushing the 6500-7k lb range.
Can some one explain those modifications that can be made to help us do this?
