The R50s are fantastic trucks, the biggest downside is the aftermarket support so unless you enjoy the challenge of making custom parts or retrofitting from other trucks keep the R50 as a DD but look elswhere if you want to build a serious offroad rig. I started with the "oh I only want a 1.5" lift, +1 tires and I'll be happy" hence the "mild/budget" wording in the title of this thread -that was almost 4.5yrs ago with lot of time experimenting, researching and customizing parts since then. Contrast that with a friend who recently bought a newer 4Runner, spent three weeks ordering parts from the ARB catalog and another 2 weeks having them put on. His truck looks like it came out of the SEMA show in less than 2 months. For some that's awesome, for others may be not but all depends on what you want.
At the stage where I am with the truck I'm just about done with anything I ever lusted after and more. My biggest complaint is the suspension...I really really really wish ICON or FOX or even Bilstein made a better suspension system for it. Where others can bomb down a rutted surface with their soft suspension soaking up the bumps I'm getting my teeth fillings shaken out due to the stiff springs and the KYB struts that just can't control the heavy springs.
