We have decided to go from seasonal camping to visiting other camgrounds. My question is my 5th wheel is about 1000lbs over what the truck is rated for. Now before I get flamed for towing over weight I'm not towing on interstates or at high speeds. If I had ordered the truck with 4.10s I would be within tow ratings. How much harm will I be doing by towing this. The truck has 50k miles.
