Been great so far on my rig, only taken it to Jacoby Canyon in Big Bear though. Mine are also re-valved to be 20% stiffer, and makes a big difference with the V8. Stays flat thru the corners and is still a very comfortable ride while being much stiffer than stock.
Driver side reservoir fits with the 05 Tacoma bracket. For the passenger side, you'll ned to get creative. I used weld-on tabs and put the resi to the frame, but have slight rubbing with 275 Duratrac's.
Can't speak for the 2.5 rears, I only have them up front. Good luck!
