You will find most companies still post the same GVWR and GCWR, but they restrict the towing to 5000 lbs due the weakness of the extension. I have no idea how much more it costs to have a fully rated extension, but full capacity towing is the exception and not the rule.
Paul, you are on the right track. Even my F-550 Host 300 needs a little modification to truly handle the 10,000# tow rating. My rig came from the manufacturer with a class V hitch and is tagged for 10,000# tow rating and a 1000# tongue capacity. The truck handle the weigh with no problems in braking, highway speeds, hill (mountain) climbing or take off from a stop but there is still a very slight chassis flex when the trailer is connected. However, the truck has performed extremely well on the 4 trips from Eastern Missouri through the Rocky Mountains.
I still need to work on the fuel economy though. Before my last trip, I installed an aFe Cold Air Induction air filter system and I picked up a little more than 1 mpg. I know that doesn't sound like much but when you are only seeing 6 or 7 mpg this made a cost saving difference on my last trip which covered about 2400 miles. I was seeing 7 1/2 to 9 mpg after the kit install. It covered the cost of the filter system in one trip.
Keep us posted with the trucks you are finding out there. I would go back to a truck camper and a class IV or 5 truck but I get in too many off road situations and the larger trucks become an issue with clearances for me.
