89supercheif40, welcome to iRV2.com. We are glad to have you join us here. Look for the data name plate for the motorhome and on it you will find the weight ratings for the safe usage of towing weights that you can carry by doing a little math. Take the Gross Vehicle Weight Rating (GVWR) and weight the motorhome fully loaded. Do not start off with an overloaded unit. Now take the the Gross Combined weight rating (GCWR) and subtract the GVWR this sum will tell you what you can safely tow behind the motorhome provided that the hitch reciver is of eaqual or greater rating. I would recommend you use (and you may to) use a weight distributing hitch to accomidate the trailer weight to the equation be carefull not to go over the maximum rating to be safe. Weigh both units and be sure your tire pressure, condition and ratings are all good as well. Good luck and let us know how you come out.
