I did the math once. My F-150 is Advertised as pulling 9500 lbs. If you figure a conservative tongue weight of 1000 lbs, truck cap and tools; I have enough cargo capacity for me and the dog. The wife has to stay home.
That is why the adds show a man towing his big boat. Note there is often no one else in the cab.
In real life my 5000 lb dry weight TT tips the CAT scales at 6200 to 6600 lbs loaded for the road, with about 750 on the tongue. With wife, dog and gear I am at my max cargo limit.
The combo pulls just fine in the hills or on the flat. No doubt a bigger TV would be nice but I do not see any reason to fix what is not broken.
