Ok, my turn to pitch in.
Got my fisrt jeep wrangler in september 94, no Rubi package on the YJ at that time. O ly came in in 2003 on the TJ. I have wheel the heck out of it. Many friends had the rubis, and some even had the rubi's front and rear axle on standard none rubi wranglers. The only strenght in the Rubi set-up t-case, is the 4:1 ratio, only good for rock crawling, specially hooked up to the 4.10 diif ratios.
The locker are a very nice thing to have, but the suspension became so good with the coil springs compare to the leafs of cj's and yj's, that I have seen many unlocked tj performe very well in regular 4 wheeling situation, even in situation when a locked and regeared YJ would have a workout.
Now, since I was doing hardcore 4wheeling, I did upgarde my YJ with 4,56 ratio, beefier axle, even better prepared than Rubi's, with 35" interco boggers, but I was running a 5 speed manual in off road situation. The rubicon T-case would only have been used once in a great while. The 2,72 was better for my most of the time 4 wheeling.
In 2015, I found my self a 2005 unlimited wrangler (the famous LJ), sport edition. Ran it with 3" suspension and wornout 33" muds or good at for travel. Only tracklock limited slip in the back, open d30 up front,lodes with recovery and pulling an off road trailer in dirt road that are way worst tha any open trafic road. Never had issues, only needed the winch of a friend ounce to pull me from behind when a culver let go under my front wheel. And by experience, no lockers (front and back would have help me much here. Only my rear winch, but would have been tricky with the trailer in tow. Faisable, but easier with a pull from my friend).
Will the LJ get the geard front 4,56 arb locked with chromoly axle and the rear currie high pignon 9" with same gear with detroit locker and and both with bigger 1/2 ton pick-up brakes? Yes, cause I have them.
Do I realy need them, not for anything not hardcore of adventure travel. But I am the type of guy that like to go forward. Would I go for a rubicon transfert case, no. Would I go for and atlas II 3 speed transfert case, yes, do I nees it, nope. And Btw, I paid 5500$ jus for that LJ.
Would I get any non rubi for what you plan to do, yes, even the 2017 sahara. But I have no care for bling my self.
So I would probably look for something even cheaper and give them better all aroumd tires.
This is all personal, and only done to help a confusing reflexion.
Have fun.
