Well, I never even had a 4x4 until my tacoma, 3 years ago. After about a 2 years of research and learning, I was considering installing long-travel, and realized that although high speed desert driving and jumps may be fun, I don't really have a desire to do that. I would rather have more travel and smoother ride over trails, as well as easier options for front/rear lockers, larger tires, etc. I also learned about solid axles and how rugged they are compared to IFS, so I got the land cruiser, plus my father had an original 1994 land cruiser that I grew up with and loved. Unfortunately he sold it about 15 years ago.
I did an old man emu lift with nitrocharger shocks and upgraded to 33" tires on the tacoma, full skid plates, sliders etc. I still feel limited by tire size and lack of travel in the front. Thus I wanted to buy a land cruiser and go all out, so I'm just in the process of gathering information and learning as much as I can at this time.
I guess my goal would be to overbuild the suspension so that I can drive over basically any trail with ease. I don't really want to get into rock crawling, but I would like my rig to be somewhat capable in that regard. For example, my tacoma would likely still take a spotter and careful driving to get through some harder trails. I would like the land cruiser at the point where my wife can drive it on most trails with just a spotter. I don't want to sound like some uneducated knucklehead who just wants some extreme rig. I've already done lots of research, but just trying to learn more. Thanks for the comments so far!
In regards to roll axis and lower link mount locations, by my understanding, the superflex uses the stock lower link mount location, but with a 3 link, you can use longer arms and just weld the mount location further back, which may allow for more travel? (genuine question, just asking to see if I understand whats going on)
