the 3715 is the bare trailer weight
4222 is your trailer as it left the factory with your options.
THESE NUMBERS MEAN NOTHING.. since you wont ever drive the RV totally empty
6000 is the max weight you should have your RV weigh.. THAT and the true loaded weight are what is important.
Once you are loaded and ready to hit the road weigh your truck trailer combination (truck fully loaded too with cargo and passengers) and see what you have. Then weigh the trailer separately and the truck separately.
