For 400 pounds or so, I wouldn't really sweat it. I congratulate you for taking the time and actually going out to the scales. There are so many TV/Trailer combinations out there that should not be on the road, you can tell the are grossly overweight just by looking at them. Or, they don't have the proper safety equipment like a WDH. So, just be careful, and enjoy camping.
