Tips --- good or bad
First and foremost, Doubles don't backup !!
You actually can a little in a straight line, but you'll jacknkife the dolly. Backing on an incline, especially if turned can whack your dolly crank. Always, Always, Always leave yourself extra room when going around a bend. If you need to brake suddenly, your tractor and lead go straight, the dolly locks and it, with your kite continue in the direction they are aimed. You need to be able to release the brake long enough to catch them before you lose control of them.
Just when you think you're gonna make that sharp, sharp U turn in the truckstop, your gonna smack your trailors. If your kite is empty, it will leave the ground on bumpy Ohio roads. If your kite is tail heavy, it follows the grooves in the road and will drift easier than usual. If they want to 3rd bed you, have the dispatcher sign for it before you leave on 3rd bed. If they refuse, call Cleveland, let them know you need them to sign when you get home. If you are on a mini, use code K, not listed on pay sheet, for all time spent waiting at intermediate terminals you deserve paid for. A turn is only a turn, after its been completed, so bring your stuff anyway. If a unit shows fresh damage (shiny), have dispatcher sign it was there in area on top of pay sheet, before you leave, so you don't get blamed later. Carry food in your bag, just in case. Carry pliers, utility knife, wire ties, electrical tape and glad hand rubbers, to do minor dark terminal repairs. Shop will give you tape, ties and rubbers if you ask. Wow, all I can think of off the top. Hope it helps. One more, whenever you stop, always check your trailer seals, glad hand, pintle, fifth wheel connections and cords, someone might screw w/your unit.
