Backing The Fifth Wheel (90 degree jack?)
I thought i would start a new thread instead of maybe hijacking one about sliders. I have never measured the degree of angle that I could back and maintain that angle without pulling forward to str...

First answer, steering wheel cut on most cars and light trucks is in the range of 36 degrees. Most motorhomes and trucks above 1 ton will have a wheel cut of 54 degrees. There are also some F350s with an optional wide track front axle that have the 54 degree cut. Not sure how this really answers the question, but those are the limitations that all vehicles have.
Second answer, basic vector physics, at 90 degrees there is zero power available from the tow vehicle to move the fifth wheel on it's wheels any further. The only thing the truck can do is to push the nose of the trailer, so unless that somehow helps park the trailer, then nothing useful is being accomplished. Well, except for contact between the truck and trailer:S. Also, when nearing 90 degrees, you quickly lose the power and ability to move the trailer anyway so getting to 90 degrees seems pretty worthless.
