Slider hitch vs Anderson rail mount question.

Is there some reason you need ninety degrees, I don't know if I can go ninety degrees ,but then I don't want to or need to. I have backed into some pretty tight spots, and haven't found the need to even pull the slider back. Just curious about this 90 degrees. Seems like a pretty good strain on fifth wheel tires ,and suspension.

I'm not talking about the weight, I'm talking about the pivot point, as in the sidewinder hitch moving the pivot point backwards...

The load on the truck is where the Anderson is attached to the truck bed (at the rails) NOT where the king pin is attached to the Anderson.

Keep in mind that you are negating the benefits of a 5th wheel hitch if you are towing with the hitch rear of the axle. The further back you go, the more it will act like a bumper pull (sway). I doubt 5 inches is that much of a worry though.

Yes, when turning clearance to the side rail of the bed!

The Andersen HITCH moves the hitch point back 5". Then the COUPLER extends the pinbox by another 5" effectively moving the trailer back a total of 10" from where it would be with a conventional non-slider hitch. Hope this clears things up for some.

Dont overthink this stuff. Many happy Andersen hitch owners.

Dang!!!! Sounds like I will need to use some Algebra to understand how this works. And Algebra was about 40 years ago. Hummmm might take me awhile. Thanks for the response.

Geometry required! With a dash of algebra thrown on top! :)

I don't know the answer, never having seen the slider in question, but my best guess would be not so much the weight shift with the hitch slid to the rear, but rather some limitation of the hitch to safely pull/haul the weight while in its rearward position.

Grab a tape measure, with your slider in the forward position, check the measurement of the wheel well above the tire. Then slide it back and do the same. I bet slid back you will see the results of the weight being shifted back. The Anderson keeps the weight in the same spot since it doesn't slide.
