Would I ever be happy towing with a half ton truck

So in reading all this, this is the conclusion I arrived at. The more money you throw at it, the better it'll tow. So the real question is, how much skin you willing to put in the "game"? Answer that first and the RV Nettters here can fix you up.
Seems you can go anywhere from a 1/2 ton to a class 8, how much money you willing to put in.
