Do you think the engineers that designed the truck had input from management to get the gross weight as high as possible? In the event of an accident will the attorneys understand that “it drove fine 1,000 lbs over the manufacturers gross weight”, or will they find the driver at fault for overweight vehicle. Maximum gross weight means the maximum weight the truck is certified to carry. As customers we can’t change the gross weight of a vehicle by adding heavy tires or any other “add ons”. The liability for the overweight RV owner is simply too great in a accident, and if the RV is involved a fatal accident..... as RV owners we need to think of our personal liability, will your insurance cover you when found to be over manufacture’s gross weight?
