towing of heavier toad

This is one of the reasons we purchased a DP motorhome. We had a Class C unit with the same drive train as the F53 units it had a GVWR of 14,500# and a GCWR of 22,000#. The F53 motorhomes max out at 26K GVWR and 30K GCWR. Most are much smaller and lighter as is likely the case with yours. I would look for the manufacturer's load plate for GCWR (Gross Combined Weight Rating) and GVWR (Gross Vehicle Weight Rating). You do not want to EVER exceed those numbers. If you are in an accident regardless of apparent fault you could be charged with negligent driving or at a minimum be liable when arguably you should not have been. There are many personal injury attorneys that will crucify you. That isn't to mention that you may have issues with your insurance company if you are overweight. They insure for "normal" risks not intentional assumed additional risk incurred due to overloading. I know that lots of people drive around all the time severely overloaded and as they say "nothing bad has happened yet". Nothing ruins a vacation like an accident.
