1995 Bounder 36' increasing towing cap 3500 to 5,000 lbs

What year Explorer. If 2011 and later with the 3.5 they are towable 4 down doesn’t matter if it’s 2WD or 4WD! You can always add a higher capacity hitch. But you need to see how the frame has been extended, it can be strengthened! And you also need to know if you have enough GVWR and GCWR to handle the 4300lbs. Anything is possible!

If this guy can do this out west with what I think is a 460, then it should be possible with what you have in mind!
