I tow a thirty six foot fifth wheel trave trailer, a twenty five foot flat bed equipment trailer with a pintle hitch, and numerous regular trailers that belong to friends etc. Nine times out of ten I'll tell those jumping into guide me on to get out of my way.
The fifth wheel I've converted over to a gooseneck. Most of the time I'll stop the truck right under the ball the first try. Keep in mind the truck is a 5500 and there's a welder and tool box between the cab and the bed so I can't see squat.
What I use is my side mirrors and the computer. You know the computer, the one that sits on your shoulders. It's not unlike shooting a sling shot or swinging a twelve pound sledge hammer drinving in one by three stakes. You stare at the target and the computer will make the calculations and do the targeting. All you need is trust.
The pintle hitch is easiest of all. That's because when I disconnect I have it about a quarter of an inch lower than the ball, it's a two and five sixteenths ball type pintle coupler. When I pull up and away there's a little bump. But what's kewel is when I back into it I feel the contact and then I feel the bump as the pintle riing drops inside the coupler. Again, I prefer to drop in straight back. But when I can't I turn to the computer and concentrate on the targeting for the computer. It's surprises people who see me back in but me and computer have this thing, we trust each other. Again, think of using a sling shot or shooting a long bow or swinging a large hammer at a small target. You concentrate on the target and trust the computer on your shoulders to do it's thing.
