Thanks for all the responses.
To answer some of the questions the generator will not be running while we travel. It will be only used when we are stopped to run one of the A/Cs. Most of the time the truck will be unhitched from the trailer.
Like I stated there will be some protection with the Diamond plate I plan on using over it. The generator will be sitting in the middle of the bed so I don't know if the exhaust would be to hot as it would be at least at least 25" from the side of the bed. If needed I would add some more exhaust to get above the bed to keep heat from the truck. It would be very hard to put my cover on it as it is hard to access my bed if I was to use it while the truck was hitched to the trailer. Being a Mega cab dually the rear fender comes out very quickly behind the cab which makes it almost impossible to get into the bed
Thanks
