Let me say that I would never tow that much weight on a 5000 pound hitch. On the other hand, my brother wouldn't give a second thought to towing it AND add a four wheeler loaded in the bed of the truck. Of course, my brother would also say it tows just fine, no problem at all. And then he would wonder 5 -6 year years down the road, why he is having transmission, or brake problems in the motor home or why the hitch gave way. Point of the story is just because you don't encounter any problems on a few trips doesn't mean that you might not be over taxing the motorhome. I agree that the engineers have built in some wiggle room on the numbers but still the numbers are set at what they are for a reason.
