Less is best. The major short coming , for us is that our rig will sleep 3 1/2 people. We have a sofa rather than the stock dinette that that has a smaller sleeping area. We often carry a roof top pod with a tent and air mattress. Your truck will handle the TC. Many here have added air bags to level side to side and raise the bed back to ride height. We found that Rancho adjustable shock absorbers reduced the sway a lot. One addition that I think is mandatory is up graded wheels and tires, if you intend long distance highway travel.
We use 19.5" "H" rated (5000 lbs) delivery truck tires and Rickson wheels. We consider the wheel/tire upgrade insurance with load we haul. Be sure to check the load ratings of the wheels and tires, many of the stock sets are marginal for TC use.
The smaller footprint of the TC makes it much easier in all aspects. We rarely rent space in campgrounds. There are many places we can boon dock at no cost or crowds.
