Is a 5th Wheel Possible for me?

[Alpo]

I am looking at a Keystone Passport 5260RL 5th Wheel to tow behind my 2013 Ram 1500.According to Ramtrucks.com my Extended Cab Ram (coming equipped with the 5.7ltrEngine, the 8 Speed Transmission, and a 3.92 Axle Ratio) should have a Towing Capacity of 10,100lbs and a Payload Capacity of 1430lbs (GWVR 6800, GAWR Front 3900/Rear 3900, GCWR 15650).The Keystone 5th Wheel has a Dry Weight of 5965lbs and a Hitch weight of 1060lbs.
There is much talk about towing 5th Wheels with Half Ton Pickups, but not a whole lot of actual examples or experience in my area.While the Weights alone appear to support the combination there are some strong Opinions and Web Based Calculators out there that suggest otherwise.
I do not believe Towing Capacity is a limiting factor here, it is the Payload Capacity that worries me. Half Ton Trucks can vary in capacities but my Truck appears typical.With a Hitch Weight of 1060lbs and a Payload Capacity of 1430lbs, this would appear to leave 370lbs for Cargo and Passengers on the axle.This 5th Wheel is one of the Lightest I have found out there, if it can’t be towed safely by my Half Ton, which 5th wheel can (if any)? Keep in mind that not “all” Passenger and Cargo weight will be felt at the rear axle, some would be transmitted to the front axle.
Travel Trailer Counterpoint – Typical like sized Travel Trailers (such as the Keystone 26RLS) have a Tongue weight of 840lbs. That weight being suspended further back on the truck should equate to roughly the same at the Axle.There should be a Algebraic formula for this, figuring a 4ft span from Axle to Tongue (the further the distance from the Axle the more weight felt at the axle). How much Travel Trailer is safe for my truck?
I do not want to be “That Guy” you see on the side of the road in a ditch!
