Unfortunately I'm not in Texas but I have a SoCal krawler. So if you have any questions feel free to ask. I've yet to go out with it due to a house remodel and a newborn that came early. But specs wise, feel free to ask.
I went with SoCal over AT cuz the only difference I noticed was the suspension and name on the trailer. And it cost a little more than the SoCal. They have their options broken down different so some options seem more expensive than what SoCal offers. In the end if you were to build one from each with the same specs you'd be spending a little more for the AT because of the frame/suspension. The AT is a SoCal cabin just on a different frame/suspension. Though I thought the frames look similar, so hard for me to say if they're the same or not.
Honestly, if those were your only 2 choices, you couldn't go wrong with either. I went with SoCal because they were really helpful. I didn't do AT because I didn't see the airbag suspension being that necessary for me. And I when I was shopping around I never heard back from them after exchanging info on what I was looking for in a TD. So I leaned back towards SoCal.
