Purchasing used Weekend Warrior Toy Hauler

Hello, I am in the market for a toy hauler. I am looking at the 2004-2007 Weekend warriors. I am considering the 2600, 2800 up to the 3000. I have done a lot of research on the law suit and know what to look for when buying. I have a 3/4 ton pick up so towing it shouldn't be an issue. However, I am unsure of what the real world weights are on these trailers. I am being told the WW underestimates their weights and I can't go off of those at all... Does anyone have any unloaded and loaded numbers on these trailers? I am also wondering if a triple axle fs3000 is going to tow better than a Fsc2800 tandem. Anyone with any experience please chime in.

Thank you in advance!
