Moving a gooseneck trailer turning radius

[DaKing]

I do own a few trailers, all bumper pull.

I'm going to rent a 40ft goose-neck flatbed so I can bring a 40ft container to one of my lands.

I know you can get a gooseneck trailer to about a 90 to the truck, right? So if I'm backing up this big trailer and angle the truck to around 90 degrees, does that affect the stability of the whole rig?

Guess what I'm asking is "is stability affected during hard turns / maneuvers"

Thanks

In short , no.

Your attachment point to the truck never changes. If the trailer is going to lean with the truck straight, it will lean the same amount with the truck at a 90.
