Similar to what a lot of guys have said. I leave them be until after I get dressed most of the way. Then open both doors. Start them up and let them run for 15-20 seconds then ease them out of the trailer. I can hold my breath for a long time. lol. Yell at the boys to hurry up. I leave them running while outside and lock up the truck and trailer, put on helmet, gloves and goggles then run them down the first few hundred yards at part throttle. Then hammer them. My buddy just pounds his stuff right from the go. I am surprised he doesn't ride them off the sled deck over the roof and hood of his truck.
