I have been running the ToughDog setup for 2 years now (53mm Ralph front/45mm adjustable rear on heavy springs) and love the setup. I do run the extended sway bar links, but that's the only upgrade aside from the shocks and springs. I did replace all the sway bar bushings at the time I did the suspension. I've run with a rooftop tent, rear swingout bumper with dual jerry cans and a fully loaded drawer system with a fridge and had zero issues at all. I now tow a small camping trailer with the tent on it and again, have experienced zero handling issues. I can't emphasize enough the value of the 45mm adjustable rears. I am hoping they eventually release an adjustable front, but the 53mm do wonderfully even without adjustment.
One thing to note: take the opportunity to examine your rear control arms (both upper and lower). My rig has driven fantastically until just a few weeks ago. I got underneath and examined the control arms to find that the 21 year old bushings have finally given up the ghost. I'm ordering the new adjustable control arms from Jason and am 100% positive that my rig will drive perfectly once again.
If you were to consider getting a new anti sway bar, then the swayaway one is really nice. But, I do not think an upgrade there is necessary at all.
