Being in SoCal, most of my overlanding will probably consist of logging roads and 4x4 needed roads.
I do NOT plan on rock crawling or doing anything too extreme: it's my DD and that type of stuff isn't a risk I'm willing to manage.
I'm thinking about building it out in this order:
33" wheels and beefier tires at the first or second tire change (depending on driving habits) -
Just to clarify, Wheels are metal, tires are rubber. You will def. not want 33" wheels
- While there is a lot to be said for gaining ground clearance by going to a larger diameter tire remember this is cut in half of the actual gain so if you get a 1" larger tire you only gain .5" of clearance. For what you are doing I would not go 33's I would suggest replacing the factory tires with stock size or maybe 275's.

suspension swap when it wears out (do i even need a lift? I would think going to something with the ability to handle more rugged terrain is the main issue along with tire clearance).
Your stock suspension is just fine for handling that terrain and reasonable weight loads and reasonable speeds
some sort of roof rack or roof storage (I'd eventually like to go with a RTT, but that's years down the road) because there's a good chance that 2 adults and 4 kids will be inside the vehicle for more than a few camping/overland trips.
This is all personal preference, I don't have a RTT and while I think they would be handy its not something I am convinced I need for the costs but having dry location off the ground with all bedding and a nice mattress inside has appeal however for the type of camping we do the limitation of having to take the time to close everything up when we wanted to take the truck somewhere just wont work I would rather some sort of trailer with a RTT on that.
If I'm keeping to relatively tame overland routes in California, Arizona, and maybe (eventually) Colorado, do I need 3" of lift?
For the couple of times I have been to CO and Moab I have seen completely stock 4runners on those trails which I would describe as far more technical and difficult then what you describe above
Frankly, most of my driving off-pavement will probably be around Big Bear in the spring and summer months.
The base of the build will be an SR5.
Opinions and guidance are most welcome!
