so i have a 1989 D150 and was thinking about possibly towing my jeep down to Moab this fall. i have a class 3 frame mount for pull behind. i also noticed, the previous owner had a fifth wheel hitch installed. are there benefits to the fifth wheel capacity wise? My jeep weighs in at 4815lbs. what are your thoughts on towing. looking for some insight on this topic as i have never really looked into it. trying to do my research but i know there are people out there that have this nailed down. Thanks!
