There is no one right solution. I think the discussion was about converting an IFS to a live axle. It is not simple and is not cheap. In an ideal world we'd all have the choice of vehicles and I'd guess about 100% of us would buy a HZJ78, Defender 110 or some other vehicle that's been proven. But we don't have that luxury. So to take something that works and works well, like a Taco, and go about redesigning it is not about reliability and simplicity. You will be looking for parts at 4 different stores, there is less scavenging parts from other trucks, you will be tweaking camber and castor angles, touching up broken welds. Scott, Chris and tons of other people here have taken Tacomas with a few changes and there is pretty much no where they won't go. I just think you've seen too many Petersen publications. There are stock SUVs and pickups going up 90% of all the trails in Colorado, even with open diffs, no lift and 31" tires. The rest have obstacle bypasses or you have to mostly go out of your way to find anyway. You asked the original question, people are just giving you opinions.
