Tough call. We have 3 vehicles right now, and the 2 my wife has are not comfortable for me to drive. Matter of fact, the Benz 350SLK, which she got when her Mom passed, I don't even fit in unless it's warm enough to put the top down, much less try to drive it. Her Lexus RX350 has all the bells and whistles, but in 4 years I've never been able to get the seat in the right position and the side of my right knee hits the console enough to be a major annoyance. So, 3 cars for 2 of us, and I only like mine. The Jeep gets our 2 big dogs and seems to do the majority of short trips- but let's be honest, I'm not doing a cross country trip in it.
I need something that is comfortable enough to drive for 8 hours, has some towing capacity and can haul the dogs and/or some luggage. I've been toying with the idea of starting my own gig, which includes a 12-14' enclosed trailer, which the JK won't tow, so there's that as well. So, yeah, it's going to be a Sequoia, Tahoe, Suburban; something along those lines.
I'd love to keep the JKU, just because I've made it mine, but 4 vehicles between the 2 of us... unless I could get her to sell the Lexus.... hmmm.
