Suspension upgrade for 5th gen

(2021 SR5 Premium) Looking at installing an Eibach Stage 2 Pro Truck Coilover lift. Plus a set of JBA upper control arms.
Right now I have 265's BFG KO2 on Method 17x8 wheels. Plan on 275 or 285 after we wear out what we have.
It's my wife's daily driver but we do a lot of overland camping. In Montana, it's forest roads and old logging roads. (For the much rougher trails, I have a pretty sweet 99 Jeep TJ.)
Our overland trailer weighs in at 1500 to 1700lbs.
**Any comments or advice on my plans for the Eibach Stage 2 and JBA control arms?
Trying to stay at or under $2000.

 

Sorry no idea on Eibach Stage 2 and JBA control arms.

But as for tires I could not find a single good 275/70R17 tire option. Either everything is Load E or Load C heavier than Load E tires. 285/70R17 is the best option (to my taste). And on the tire brands, BFG KO2 Load C is my preferred choice from the tires I've tried although Goodyear Wrangler Duratrac is better in snow and Falken Wildpeak SLs ride comfy on road.

 

Here is a couple pic's of the overland trailer I built

 

In my jeep world I'm hearing good things about the
Mickey Thompson Baja Boss A/T

 

I see 4Runner folks also moving to Baja Boss A/Ts. There was a thread recently if I'm not mistaken. There is a Falken R/T thread also.
