Towing Issues: 5th. wheel towing new 2007 Toyota Tundra, wheel camper, bumper hitches

Question
I like the new Tundra a lot;  it is rated to tow around 10,200 lbs. and seems to have an impressive array of equipment to do this.  I have a 5th. wheel camper that has a max load rating of under 10,000.  A guy at the Toyota web side tells me via the chat on the official web site that towing a 5th. wheel camper would entail reinforcing the bed and frame and might raise warranty issues.  I can't believe what I am reading.  What's your take on this?

Answer
Well this is out of my area of expertise, but I would agree that the reinforcement of the bed and frame mounts might have to be done...

I have to say that while the smaller pickups are getting stronger every year, they still do not have the "BEEF" of the full size pickups..

Only thing I can say for sure, is that in the towing of accident vehicles which were pulling trailers, I tend to see a lot  of big trailers (5th wheels and bumper hitches) being towed by pickups that are too small  ( 1/2 ton trucks or so)
