I'm thinking about getting a ToyHauler 5th wheel. I'm concerned about the hitch weight. I only have a 2500 and I'm seeing a lot of the 5th run about 1500 hitch weight. What can I expect at that weight? Does the truck sway alot? If any of you are running more weight do any of you have airbags? How hard was the instal and how big was the difference? My truck has overload springs on it... Can it handle a 1500 hitch... . Also is 13000 really the max like the owners manual says??? Could I pull more as the truck is pretty stock. .
