We have a 1990 Coleman Chesapeake pop up, 11-12' folded up and I'm trying to figure the weight on it. We want to take it out ths weekeknd and use our Explorer to pull it rather than the truck, which is broke down. The truck has a regular class 3 hitch on it but the Explorer doesn't and I haven't been able to find anyone that carries a frame hitch for it (they can order one, but not by this weekeknd.) The bumper has a towing weight of 3500lb and the 1 7/8" ball has a weight rating of 2000lb. Would that be enough to tow this camper? I can't see the camper weighing 2000 lb. The park is about 1.5 hrs away and this would be a one time deal, somemthing to get us out this weekend til I can locate a regular hitch.
