Whats the biggest enclosed cargo trailer I car pull

[jcavender75]

With a 2002 ford explorer all wheel drive with a V6. I put a hitch off a v8 explorer on it. The hitch is oem factory hitch. Thank you

I would still refer to your manual for the weight limit, even if you put a class 3 hitch on your truck still has the guts for a class 2 hitch so I am assuming under 5000lbs.
