Long Bed or Short Bed?

Can I assume that only a long bed will do for a 5th Wheel?

You can make that assumption. EXCEPT for the last 29 years I have towed fivers with short bed trucks. In the beginning, max turning angle was about 65 degrees (no sliding hitches). Now with notched front cap, the angle is about 85 degrees, no problems. Still don't use a slider hitch and never damaged any of the 4 trucks.
