We have towed our Jeep Cherokee behind our 2020 Bounder 35K for over 22,000 miles without any protection. No damage what so ever and our travels took up all over the USA and right across Canada. The engine compartment got very dusty but nothing a pressure washer didn't rectify in short order. We bought the Jeep used thinking it would get beat up that that didn't happen. Also used the Blue Ox gear.

We tow wrangler and I applied 3m clear protective plastic and worked out very well towing over 20,000 miles. We bought a yoga mat at Walmart and apply it on windshield and tuck in doors.
