I was looking at the Titan last year and ended up with the Burban. I don't regret my choice. Towing capability is excellent. Interior space is excellent.
We are just coming back from a trip to Canada with it, comfortable, plenty of space. Only point is the gas mileage that is not really good, but since it's used only for towing, family trip and go pick heavy or big stuff at the store I can live with that one. By the way 4' X 8' fit inside with the back door closed and 11' will fit between the front seat with the back door closed. For stuff like mulch I either borrow or rent a utility trailer.
Instead of looking only for one vehicle why you don't go the route of having a nice, used, preferably low mileage GM 1500 HD Crew Cab for towing and the mulch day, and have a small, used, sport car for daily driving to work. That way you have something fun for daily driving and good gas mileage and you have the truck for the rest. With that limited mileage on the truck you should be good for a long time.
Money being no object, we will be having a BMW 3 series or Benz C class for Kathy, a Boxster S for me, a van like a Honda Odyssey for the family trips, an other Porsche for the track, a Dodge Mega cab diesel, wait I said money is no object, scrap the Dodge, an FL60, 4 door instead
