I have a 34foot Hemisphere.
I would consider it abusive to the truck to pull it with a F-150.
I would also consider the driver and owner of said F-150 to be out of his mind to pull something as long and heavy as my Hemisphere.
It is one thing to get the RV going, but completely another to control it and stop it when needed.
I have driven everything under the sun and have had a Commercial Drivers License for 45 years and still drive Commercially. Don't take such a chance with your life and property and the lives and property of others. Get a bigger truck or smaller RV.
