We just completed a 2,000 mile trip from Albuquerque, NM to Puerto Vallarta, Mexico towing a MacGregor 26M with a Jeep Cherokee Sport,2000 6 cylinder We averaged 55 - 60 mph all the way until Tepic,(2 hrs from PV) where we encountered mountains and that was tough, had to stop on one hill to cool down but we made it. We passed the border at Nogales to avoid the Durango mountains of Mexico. 4 day trip, we stopped in RV parks and slept and cooked on the boat, lota of fun for 2 60 yr olds, first time Macgregor owner
