As I said, being really conservative. We haven't tested the setup yet as we don't have the drawer system. That weight is also an estimate from the owner, not sure what it actually is.

70# is for stove, pots, pans, cutlery, dry goods, propane, chairs. Again not sure what this number will actually be.

Table is included with the drawers.

We'll definitely be refining and reducing the list as we test things out leading up to the trip, but that's my initial list.
You got some great replies from experienced people but I will add something else.

First of all, reality check.

Payload is 1,550lb. Carrying 1,200-1,300 is totally fine. We went up and down the Maze district of Canyonlands fully stock with about 1,000 lb total weight with zero issues of any kind. I got sick so the one trail left was the hardest one but I walked the hardest ledge since we camped nearby and it would not have been a problem.

If you drive something like Elephant Hill with 1,200lb on stock suspension, you would have to be careful with the bumpers on a number of spots but it can be done. Some scraping is likely.

I am giving those examples because those are areas where you actually have to carry heavy weights for any camping. In the Maze you carry your own toilet with the contents as well on the way out. Usually, you will be driving difficult trails with little weight.

And it can be done fully stock. I doubt you are driving the Rubicon on your first trip anyway.

NOW, with reality in place, while stock does the job, it also sucks. And I am as big of a fan of stock as anyone. How bad stock is you will realize once you replace the springs. I did springs first on stock shocks and then a full upgrade so I could understand very well the various differences. I am on my 4th set of front springs.

The problem with stock springs is that although they technically carry the weight over pretty rough terrain, they do that at the very bottom of performance, meaning that 1/ if you make one mistake on a rougher trail, you will scrape a bumper and 2/ if you dare pick up any speed much higher than walking speed in undulating but not hard terrain, you will bottom out often and sometimes badly.

The problem with just replacing the springs is three-fold 1/ mismatch with the shocks as the shocks are too weak to control the springs, 2/ potential longevity issues for the shocks, 3/ lost travel in the front--and travel matters! plus failure to gain travel in the rear.

This is, then, the argument for upgrade. But lots of people here then go all the way into racing setups.

The following will do the job for you offroad and on, judging from reading a lot and talking to people here while also making changes to my suspension.

1/ Eibach shocks and rear springs with your choice of front springs (no need to go for their huge front lift). I have 1" Eibach rear springs and zero issues whatsoever with sagging even with a bike carrier in the back. Worst case, I am at the height of an empty stock vehicle.

2/ Dobinsons twin tubes with Dobinsons springs all around. I had Dobinsons front springs and they were PERFECT. I liked them better than my 600lb Bilsteins, which were too soft, and better than my 650lb current Bilsteins which are a tad too stiff.

3/ Bilstein 6112 with 600lb front springs (unless you do a lot of offroading in the Southwest in which case 650lb are much better) and your choice of rear shocks and springs, which includes Icon 2.0 (which is what I have), Fox 2.0, Bilstein 5160, and Eibach as well.

In any case, you will not be racing with those weights so an Eibach or a Dobinsons setup will be very useful for WAY less than 1,000.

The best price you can possibly get on the mid-range setup I have is about 1,150 for the shocks and springs, assuming you don't pay extra for another set of front springs like I did. That said, I am not sure my setup actually adds any value over Eibach or Dobinsons except for being more adjustable in the front. I have not tried either of those.

Next, you don't need a monster lift. I have 1.25/1 and I will drive all but a handful of trails people with 3" would. What you do need is stiff enough suspension, so that the front does not dive onto rocks and that it does not hit if the terrain surprises you when driving a little faster.

Finally, most of the good info you will find is too specific to racing or too related to racing. I have found out that contrary to what racing knowledge suggests, the springs are much more important than the shocks on an adventure vehicle, which is also what a lot of old timers say. You are not moving at some crazy speeds with 1,200 lb of cargo or with kids or with a dog. But you do want to move at decent speeds and not crawl some unremarkable terrain. The springs get that job done. The shocks just need to be a good enough complement for the springs.

When it comes to overheating, I got my 6112s and Icon 2.0 untouchable by bare hand after less than an hour on an easy dirt road. A mildly climbing dirt road in Arizona in August can do that!

EDIT: one more thing, I don't think you need aftermarket UCAs to gain extra wheel travel though you would if you want a lot extra tarvel. Toyota advertised 0.75" front wheel travel extension with the TRD Bilstein and I have found this to be true with my 6112s. They also advertised 1.5" of extra rear travel, which is true with my Icon 2.0 shocks as well. You may not get that benefit from Eibach or Dobinsons. Travel is extremely important. I had a Subaru before so I never cared but this is a different beast and while much more capable it is also much less stable so travel helps with both capability and safety.

Sent Mike a note, hopefully he replies!

Originally I was looking at the Fox 2.5 or King coilovers with reservoir. Obviously this is on the seriously pricey end, and would love to get more info on those and the benefits of such a serious upgrade.
I'll tell you how I ended up with KINGs and how you can save some money by not doing what I did.

When I started modding the 4Runner for offraoding, I had the 6112/5160 bilsteins with T12 rear coils. Smooth ride, minor lift, and handles great. However, I found myself transitioning from weekend excursions more into weeklong+ trips and more fancy gear being stuffed in accordingly (overlanding?).

By the time I decided to move on with the steel rear bumper, I found myself stuck with a suspension setup that can no longer carry this weight properly. Re-did it with KINGs and ICON overland progressive rear 3" coils and now it runs perfect for my needs.

Lesson: Had I known the final goal of the build, I could have saved the $$ by doing the suspension once, not twice. Find out your budget, off-road needs, desired lift height, addtl constant weight + trip gear weight, then buy the best you can afford and cry once.

Keep in mind upgrading suspension for a higher 'constant' weight with firmer coils will usually result in a harsher ride when driving unloaded

If you go the $$ suspension route, IMO you HAVE to go with shocks with compression adjusters option . I also did the extended travel option but you'll need UCA's for the front.

Most of my trips now are a few weeks' worth at a time, with the rear steel SSO bumper with spare mount + 2 Jerry cans, 50qt Fridge, lots of gear, roof rack loaded, I find myself giving it an extra 3 to 4 clicks of compression and it drives great. Still nice and plush when unloaded as I lower the compression down.

The majority of our travel is on roads and fire roads, but we also get on a fair amount of lesser traveled rougher roads to remote places. I'm a bit split on the lift, I feel it would help, especially with the heavy load we'll be carrying... Not leaving until May so we have lots of time, but want to get things sorted out sooner than later!
Yep. Those ones. The airlift and firestone bags are very similar, but the key difference is that the airlift bags are shorter and fatter. The result is that even at minimum air pressure they are still putting a good bit of force out on the coil springs that cause a harsher ride unloaded. The firestone bags are taller and narrower. When at minimum pressure they don't expand out against the coils the same way, so they ride a bit nicer empty.

I think a small front lift really helps with ground clearance up front. But the stock 4Runner will take you almost anywhere you probably want to go. I'd spend the $ on a hidden winch up front over a lift and larger tires for what you're planning to do. The winch will get you unstuck if you happen to get in over your head. And keeping stockish height will make the highway cruising a lot nicer and that's where 99% of the miles will be.

You could probably save some weight sans the second cooler. I mean you don't need a heavy cooler when you also have a fridge. I rotate items. For instance sodas can be kept out and when I start to eat more and empty out space in the fridge then I throw in a few sodas at a time. So I would ditch the second cooler. If you get one, get something like a Yeti Hopper with the ice packs which would be good enough for some drinks and weight a lot less than a hard sided cooler. Another idea is that instead of a second cooler just get a bigger dual zone fridge/freezer instead. You'd save weight, cargo space and then have a freezer side.

Dry goods probably won't be 70#. I guess you're talking about chips, bread, fruit, cooking utensils. Get a set of lightweight aluminum or titanium cookware sets. Something like the Sea-to-Summit, MSR, or GCI stuff. I wouldn't get any heavy cast iron or anything like that.

Water. If you think that's how much water you need then I probably wouldn't skimp on it. I guess that's the one thing I'd rather have too much of then too little depending on how remote you'll be.

TBH though, in the US you're probably not too far form a gas station, grocery store, wal-mart, target etc etc. You don't have to carry everything with you at once. Reload and refuel as you go and I think that can save you some weight on the foods, dry goods.

Take a listen to the overland journal podcast. I think it's a good start for build and travel tips.

Right but he's given a very realistic load weight list for his travel and build. The weight of the Trekboxx is essentially the same weight of a rear bumper. The bike rack and two heavy mountain bikes also add a lot of weight, just as much as a front lo-pro and winch. Your weight might be more into armor, his weight is more into the RTT, drawer system, fridge and bikes. It's just distributed differently.

I'll get in touch with Dobinson, have definitely been seeing their name around here a lot.
The benefits of being able to rebuild is that if they do get worn out or blown you can rebuild them or have a shop rebuild them. If you got with something like a Bilstien, sure they will replace them, but you have to pay for new ones, cross ship, or have your truck down for a week or more while you are shipping the shocks back to them and waiting on them to process and turn around the new ones. If you are doing 6 months of continuous overlanding/off-roading they may be something to consider.

The other thing that has been mentioned and deserves some more thought is that if you build your suspension to handle 1,200 lbs it is going to ride like crap without that extra weight. Last year I swapped my rear springs for heavies in anticipation of my rear bumper, there were some snafus and the bumper was much later than anticipated. The vehicle rode horribly, bumps during high speed turns (Interstate) could be almost terrifying while the back end figured out what it was going to do.
