GVWR & Towing

I am about to purchase a 37ft Class A RV, and I want to make sure it can tow my tow vehicle. The RV is a 2013 Thor Challenger 37DT. On all the brochures I have found online the GVWR is supposed to be 22,000 with a GCWR of 26,000. But on the Title from the dealership, when the vehicle was purchased new in 2013 it had a "Scale Weight" of 24,582 lbs. This Scale weight is listed on the Vehicle Title. Is this a problem since the Scale Weight is over the GVWR, and how much additional weight can I tow?

This was confusing because I do not understand how Thor would manufacture a new RV 2,500 lbs. over the GVWR.
