I'm still using the Anderson hitch. I raised the ball height in the hitch but still have a clearance issue with the bed of the truck. This reduces my turning radius when pulling or positioning the fifth wheel. I have an F350 Diesel long bed quad cab that pulls the Solitude model 344GK effortlessly. Jealous of the guy in the YouTube video with his GD Momemtum turning at ninety degrees to position and park without any problem clearing the truck bed walls with the gooseneck. Alternative is a different hitch that is apparently much heavier. I can easily install the Anderson hitch myself.
If you go with a true goose neck hitch like https://www.reeseprod.com/products/pin-boxes/goose-box/uW9rVuV4JAj75t!ZHQnotJoVbxIFMqvl the only thing you remove from the bed is the ball.
