2005 Ford Explorer 4.0 l engine 4x4. Rated 4800 lbs and comes with a class 2 hitch. Had a class IV hitch installed and bought a camper that wieghed 4200 lbs. With the kids and all equipment we were well over the weight limit. Also the truck has the aluminum alloy rims which 2 have sheared 4 out of 5 lugs and stripped the holes in the rims. I think that this was caused by being so close with the weight. Anywho I have upgraded to a Chevy 3500 Express van. I will never pull anything with the Explorer except a utility trailer again. Just saying anything you get should be under 3000 lbs so that will limit you to popups or super light trailers
