Howdy. I'm not sure I understand the one portion of your question where you state you are over your GVWR. Are you referring to the truck or the trailer. If you are referring to the trailer the only way you can be over the GVWR is to load it over the GVWR. Remember, GVWR in a trailer is your friend. The higher the number the better. Would you rather have a trailer that is loaded to 8000 pounds have a GVWR of 9000 pound, 10,000 pounds, 11000 pounds. Always pick the biggest number. It is indicative of axle size, tires, rims brakes etc. GVWR is a rating, not a weight. GVW is a weight. Always keep the GVW to a number your truck is capable of towing. As far as GVWR, bigger is better. I have seen dry weight trailers of 6300 pounds on lots with 7000 pound GVWR. I have also seen the 6300 pound trailers with GVWR's of 10,000 pounds. Which one do you think is built better?
Hope your trailer search goes well. Happy trails and safe journeys.
