Thanks everyone for your replies.

Yes, I am already towing a 5th wheel at a dry weight of about 10,500 lbs and both my wife and I find that manageable. And yes you are also correct that many campgrounds we visit can fit us in but just barely. So an additional 5 feet and 3,000 lbs with the new fiver we are considering are my main concerns. Is the more space, residential fridge, capacity worth the additional stress and will I find towing a bigger rig much different than what I have today?
