I have had traditional fifth wheel hitches (slider and non-slider) in the past, but I went with the Goosebox on my GD Solutide 380FL, which has an empty TW of 3000 lbs. I have the B&W Turnover mount in my truck and the 4” offset ball in my bed weighs 15 lbs vs 280 lbs for the B&W Companion Slider. The weight savings alone was a huge factor in my decision.
I can put my ball in and hook up my camper by myself without using an engine hoist or front loader to put my slider in. I set my camper to hitch height, use my in-bed camera to line things up, and drop the Goosebox hitch right onto the ball. The chains are easy to attach when you have an Amp Research bumper step on the driver side, so that is not an issue for me either.
With the 4” offset ball, I have never had an issue backing into spots with tight clearances, so I really do not miss the slider.
