Since I am that dude, I'll jump in here.
You can do long travel, and a lot of people seem to be jumping on that fad in the 5th gen market, but not a lot of people are either doing it right or doing it all out.
[MENTION=76550]cbielat[/MENTION] and I have probably been running these setups all out for longer than most, in totally different applications. He's been using his to crawl, I use mine to go fast. There's a big reason I haven't gone to 37's and that's because while cbielat gets that 1 more inch of ground clearance, it's at the expense of travel, which is painfully essential to me for what I want to do.
I think if you asked both of us if there's a compromise when doing systems as extreme as ours, we'd both honestly say yes. I have custom rear shocks, I have the first anti-rock setup in a 4Runner, and I also have a tremendous amount of labor I have to do every few weeks to keep my long travel working and sounding as factory as possible given the components involved.
This is why I say if your vehicle is primarily a daily driver (I work from home mostly, and my vehicle mostly gets used as an adventure vehicle despite it being my one and only vehicle) then you have to consider how it works from a maintenance standpoint, and how it drives. The minute you go long travel expect to do ALL the servicing on the suspension yourself, no service bay is going to help you when a shock goes bad. Are you prepared to do that? Just getting one of my front coilovers requires 30 minutes and about 5 ratchet straps just to compress the bypasses to allow me to access the coilovers.
As for handling, I've tamed it as best as possible, but it's cost a lot of money. It's also cost a lot of time from trial and error. I'll be honest, I've seen a lot of people add long travel to their 4Runners, and the vast majority of them are half assed. And to do it right requires a LOT of labor and time, and money, to build a system that doesn't beat itself to death, but you can drive long distances. I also tow, which means giving up a sway bar in the rear would have been super sketchy. Adding factory sway bars would limit the travel.
I have my setup tamed on road as best as possible, but 16.5 hours back from FJ Summit was exhausting when you're doing 85-90mph to get home, and the vehicle still wants to get away from you if you're not careful.
There's a lot I felt I had under control on my build before Baja, a lot I realized I didn't, then I rebuilt it and revised, and a lot of questions I have that I'm sure will be answered next June if I get the chance to do Trail of Missions 2019.
