Anybody Towing A Wide Body 5th Wheel With Short Bed?

We pull an Artic Fox 27-5L with a 2016 F350 short box crew cab and an Anderson rail mount and could not be happier. 8000 miles this summer and 33 different campsites and not one issue. It will not go to 90 degrees but I could care less. When I got the trailer in June I took it to a dirt lot to see how far it would go. When I saw how much it was twisting the axles I have no interest in turning that far.
