Sometimes that rating also indicates how much total weight capacity there is for towing. So even though it may indicate a 5,000 lb hitch, the difference in the GVWR and the GCWR is only 5,000 lbs. You can use that up with other stuff you may be carrying in the coach. Look at all the weight ratings on manufactures web sites (or brochures) and calculate how much capacity you have for the motorhome, your stuff, and the toad/trailer.
