We have a brand new set of walkie talkies for this season and a new set of those flourescent yellow magnetic sticks. With a diesel, it is tough to yell instructions back and forth. To make matters worse, last year Dodge had a "safety" recall on the diesel trucks such that if you open the driver's side door while the truck is in gear, the horn starts blaring "honk, honk, honk" It really makes you popular in campgrounds.
As mentioned previously and in the other thread, getting the vertical angle to match between the truck and the hitch makes things work so much better. You just use the weight distribution rods to tilt the stinger to the right angle and the trailer jack to set the height. The hitch helper is nice too, even for a conventional ball hitch mount.
