On my class A DP the hitch is only rated for 5,000lbs weight carrying, 10,000lbs with a weight distributing hitch. The Freightliner chassis is plenty sturdy, it is just the hitch itself that is limited. Always remember to find the weak link in the chain and make sure that it is not overtaxed. My other weak link is the transmission. It is only good for about 7,000lbs over wet coach weight. Just because the hitch has a 10,000lb rating doesn't mean that the rest of the vehicle does even if the manufacturer advertises that it does, which mine was.
