As posted before, I have a GMC 4 door short bed 1/2 ton truck. We have ordered a new 2H GN aluminum trailer and we are trying to figure out the best way to go. We at first thought the 9" would give us more turning radius. However, after Hubby started figuring things out by making a diagram, we are thinking the 4" will do better. We have 27 " from the back of the cab to the middle of the ball in the truck. It is a turn over one. Here is how he came up with this.

The 4" ball extender moves the ball backwards. But the 9" extender moves the coupler back and the ball stays the same. So that way the pivot point is entirely different.

So he is thinking the 4" will give us more turning radius without knocking out the glass. Plus the 4" extender is almost $200. cheaper.

I told him I would post this and hopefully I didn't mess it up. He had to make a wooden trailer front wall model and pivot it to show me what he was talking about so I could understand. Is there something that we are not comprehending?????

PS...I know we probably need to go to a 3/4 truck. Hopefully, we can put that off for a year or so.

Thank you for your posts.

I guess I was just surprised that the 4" ball extender gave us more turning radius than the 9" coupler extender and it is half the price. I just wanted to get more input to make sure we had that figured right.
