I’m about to purchase a 2017 EX-L with 55k km and will have it inspected beforehand by CAA (Canadian equivalent to AAA). How do I get them to verify that there are no injector nor tranny issues? My first Ridgeline and first post. Thanks for sharing your expertise!

My 2018 Ridgeline noticeably vibrates when towing my boat between 25-35 mph. At 60 or 70 on the highway, it's fine. The boat, motor and trailer are about 2,500 pounds so capacity should not be an issue. The dealer - Honda North in Topsfield, Mass. - wants me to bring it in towing the trailer...
