JK shopping and need some opinions

I have just started my JK shopping. Had a CJ many years ago and want to get into one I can take the kids with me on the trails. Here is my plan for the Jeep. It is not a daily driver. Probably 60/40 pavement and trails. I am planning a 3.5" lift and running 35's. The Jeep will have an automatic trans so everyone in the family can drive it. I am planning on a gear swap to 5.13's also.

Now the questions.... For the basic platform...should I start with a 2010 Rubicon or look at a 2012 Sport??? From what I can see in stock form they are roughly the same price point. The 2012 has the better engine...but the 2010 Rubicon has the D44 front diff and the E-Lockers. If I am doing gears in both and buying tires/wheels and lift kit for both.....which is a better foundation?

Will the D30 survive the abuse of 35's with 5.13 gears in her?

Thanks for your help

no need for 5:13 gears in a 012+ auto with only 35". 4:10 is fine. The older 011 down in the auto YES 5:13 with 35"s. The auto in the 012+ is nothing like the pre 012's. it has a full step lower 1st gear and is almost 2x stronger. Withe added power of 3.6 and its flat torque curve makes The 012 Rubi/s with their 4 to 1 low range a real beast off road.

I would go with 2013 sport with max tow package and get 3.73 to start with , I would only lift it 2 1/2 inches because of the cost of going higher and 35s will fit and from what I read the Dana 30 and 44 really need to be beefed up to run 35s there's a thread about running 35s on jks Check it out

The money you’ll save in gears alone makes it a smart move.

If you aren't on the road too much I'd go for the Rubi. We had a 2010 Rubi rental in Moab last year, the power feels totally fine off road after it goes through the 4:1 transfer case! You'll have to regear for 35s, but I'd say a good trade off for the axles and transfer case. Also you're probably not too worried about the interior if it's seeing that much off road
