I have a gmc 3500 diesel dually chassis cab that I would like to put on a 14 foot living quarters. The prices I have found for this type of custom work is super high. I would also like the option of removing the living quarters and using the truck as a flatbed. I can buy a new travel trailer that is pretty close to what I want for about $10,000. I do plan on cutting a pass through in back of the cab no matter which way I go. What do you think, would it be safe to ride in a travel trailer bolted to a flatbed?
