According to a
recent brochure, the ratings for your coach are as follows:
GCWR (Gross Combined Weight Rating): 22,000 pounds
GVWR (Gross Vehicle Weight Rating): 14,500 pounds
GAWRF (Gross Axle Wight Rating, Front): 5,000 pounds
GAWRR (Gross Axle Weight Rating, Rear): 9,600 pounds
Hitch Rating: 7,500 pounds horizontal, 500 pounds vertical (that is, tongue weight)
CCC (Cargo Carrying Capacity): 1,720 pounds
If you are unfamiliar with these terms, see
this link for definitions.
Since you own the coach already, the "real" values should be shown on a label in your coach. You should review that label.
One of the problems with long Class C coaches such as yours is that they can't carry much cargo (low CCC or OCCC). You should weigh your coach loaded and make sure the Gross Vehicle Weight and Axle Weights are within the limits listed on the label.
Weights and ratings affect the decision to tow flat or use a dolly.
If you tow flat, you should be able to tow up to 7,500 pounds.
If you dolly-tow, the tongue weight of the dolly (with its load) must be 500 pounds or less AND your coach has to weigh no more than 14,000 pounds (loaded, without the dolly attached) AND the rear axle weight must be less than 9,100 pounds (with the coach loaded, without the dolly attached) to stay within the ratings.
I hope this helps.
