Why is stopping the RV faster bad?
Your towing components are rated to tug up to 5000 lbs. If the towed pulls against the RV stopping it faster, you will exceed the rated capacity of your tow package. You are now trying to stop the weight of your RV with a 5000 lb tow package. THIS IS A SERIOUS PROBLEM THAT WILL CAUSE TOW COMPONENT FAILURE OVER TIME.
