In 11 years of towing a 15600# fifth wheel we used 4wheel drive in relation to towing one time on a wet grass campsite pulling up a small hill . But it is the kind of option that when that day comes, and it will , you will think back and question your decision to go with rear wheel drive. We currently have a rear wheel drive truck but we did it to increase our payload capacity since we now carry a TC and are willing to take the chance on needing 4 wheel drive at some point. We have been on wet grass with the TC and have not had any problems so far . Our TC puts almost all it weight on the rear axle so when I do get stuck it will be my rear tires sinking into grass or mud andI probably would need a tow anyway .
