"Anything's possible",.....but you will find out it's not worth it. I've even done it with my big Dutch Star. And, 4 motorhomes ago I tried a front hitch arrangement. I found out it's not the way to go either.
The only way I will do it now is for me to tow the boat with the motorhome, and for my wife to follow me with the GMC 4x4 Envoy. My Envoy is the perfect vehicle for launching the boat, and the perfect vehicle for running around when living in the motorhome, and the perfect vehicle for towing behind the motorhome (on non-fishing trips), and the perfect vehicle for use as my daily driving when we are at the home base.
