I am by no means an expert in this field - Sorting through all the opinions on the TTORA site - which took about a year - there was a great thread between Donahoe and Camberg - many great points were brought up.
I did not know Scott at the time so I was on my own (Scott is a researching son of a gun ) After all the research - I went with my gut feeling and choose Donahoe - there was something special in his posts to the group - The coilovers are very well built and now in hindsight really gave the tacoma a more solid ride on the highway- not to mention how it holds up on the trails (especially washboard roads) Out in death Valley I was able to do a Baja Style ( read high speed) test run on the worst road conditions without worrying about hitting anyone - the coilovers proved excellent in keeping the truck on the road no matter what speed or road condition - I am kind of a buy the best and cry once guy.
On the Uni-Ball upper arms - I asked the opinion of a few knowledgeable Tacoma folks - they all felt with the type of use I was into - there was no real gain to switch them out - They do appear to be more stout when viewed side by side with OEM - I figured I could spend the $$ elsewhere -If I have a problem with the OEM's I could upgrade then
On the Deavers - I did not plan on a rack and the rooftop tent - this and a loaded bed will send me over the weight limit and I loose quite a bit of travel - Right now I am sitting nice but once I load the bed the springs are done. I am going to try and get the ten leafs ordered and in by Nov 1 - ready for Surf & Turf
For me this is all a great journey of learning, trial and error, and finding what works best for me and the Tacoma over the long haul - I have never been into finding cheaper solutions, just finding ways to pay for the finer things in life.
So far the Tacoma has never let me down on any trail in AZ-Utah or CA and most folks I have had the pleasure to wheel with always seem impressed with its abilities to climb over obstacles and keep moving
Thanks for asking!
