The label in your owners manual is generic and does not apply to your or any real motorhome.
Look on the wall next to the drivers seat, should be a label
(Chassis Identification Data) giving the GVWR which is the most your MH itself can weight. Will also show GCWR (Gross Combined Weight Rating)which is
Combined MH and trailer/Toad weight.
But: You can not exceed the hitch weight rating which should be on a label on the hitch itself. As an example-(may be different for your specific MH) It will show 2 weights (500/5000) 500 is the max tongue wt and the 5000 is the max weight you can tow.
Your specifications should be the same as the 1999 Cruisemaster. It's chassis weight limits are the same with or without a slide.
