Randy and his crew added adjustable air shocks to my pick-up and did my brakes. My vintage travel trailer, a 1973 Avion 28' and 6000 lbs, now pulls much better. I wish I had done the shocks for my first 18,000 of trailer travel. I am now ready for the next 18,000 miles. They looked the truck over to make sure it is safe and I trust that I will be fine for my up coming travel event.
