Now this is me-some people will disagree, some will probably jump me, some will agree. I've had my 02 cranked way high, cranked up just a little, not cranked at all (cv angles parallel with ground), and lowered. I am going to tell you your front end is too high and that's where your harsh ride is coming from. Your cv angles aren't the most extreme I've seen, but they aren't great.
The torsion bars raise the truck the more they are twisted. As you raise the truck, you basically twist the bar harder to overcome the weight more. As you do this, you also lose the give of the 'spring' to absorb the bumps and imperfections of the road. If you lower the front down, and make the cv's and control arms more parallel with the ground instead of angling down, it will give the torsion bar more ability to absorb and dampen the bumps. Yes, the shocks absorb the impacts, but if the torsion bar 'spring' is too stiff to give, then the shocks can't do much.
The rear is going to be kinda stiff with no load, but its not horrible. The airbags are made to help support the load if you have too much squat when the weight of the toyhauler is on. I've not personally used the sulastic shackles, but have heard positive about them-several on here.
Like I said, there are people who will agree with my words, and there are people who will disagree. And part of what we can't tell is if the harshness you are talking about is from the front or the rear. But coming from a guy who has had seven different classic-body trucks on all levels except completely slammed on the ground all the way around, that is what advice I can give you
