As someone has already pointed out, nothing takes the place of experience with your own equipment, thus I would suggest you change nothing at all until you establish your own usage pattern.
Regarding handling, in my experience a higher center of gravity in the wind does not feel the same as a full load in the bed. However, I would opine much of the improvement in handing has more to do with time behind the wheel than a boatload of aftermarket parts.
There is a learning curve to truck camping which is fairly steep starting out, but not very high.
We are catching Florida sunshine now and will soon be heading home to prepare to head West for the summer/fall. Maybe we’ll meet on the road. 🙂
