Towed my 'new to me' '66 GTO 650 miles home over the Cascades with my '05 Tundra 4x4 and a U-haul trailer with zero issues. The trailer had a long tongue and stabilizer struts and the only time I knew it was there was pulling grades, and that just required more throttle. The 282 HP V8 with 3.91 gears made it an easy trip. The GTO was complete, with all the trim in the car and in my truck bed.
