Suspension upgrade with camper topper

Hello! Not necessarily new here but first time posting.
I’ve got a 2020 sr5, ~65,000 miles. Generally doing easier moderate trails every couple of weeks in CO.
I’m getting a camper/topper on the back (tune m1) weighing roughly 450lbs without gear and whatever interior build I decide to do, but I’m thinking ~700lbs Total for trips.
My plan is to get the deaver stage3 with bilstine 5100s in the back and 6112s in the front with 2” lift but adjustable to 2.5, so I don’t have replace the UCA right this second.
I’m new to all the suspension research, particularly with the camper top. Does this seem like the best bang for the buck? Is there anything else I should consider? I’m mostly concerned about managing the new permanent weight in the back end off road.

 

I would consider rear 5125's instead of the 5100's. Even with that weight you will likely see 2" of lift and the 5125 is for 2-3.5" where as the 5100's are going to be topped out at 2"

Upgrade your rear bumpstops and atleast add a 1/4" spacer to your fronts. Some of the 6112's come with the front bumpstop spacers.

You don't have to get UCA's but it will ride better with some additional caster from them.

6112's have a top clip of 2" of lift for the 3rd gen. You can go with the 650 spring for a little more height and support or add a 1/4" spacer if you want an extra 1/2" of height. Anything higher than 23" center of hub to fender is going to ride a little rough though.

Rear Extended Length
5100 - 22.22"
5125 - 24.38"
5160 - 23.63"

Examine your rear brake line length at full droop too.

 

If your budget will allow for it, what you are trying to accomplish is 100% what we focus on. We can put together a shock and spring package for specific weights and make it ride comfortable and controllable. Leaf springs would be a great start, but generic off the shelf shocks will only do so much. A set of tuned shocks with correct spring rates will really help control that Tacoma with that much weight. Happy to review some options if you're interested. Until then, here are some packages we have to offer: https://accutuneoffroad.com/product...-tacoma-2020-2005/mid-travel-suspension-kits/
