Location: NJ during the week Delaware on most weekends
I have a stick also and use 4hi, first is fine but I have to wind it up because second will bog down if I don't. Last year it wasn't so bad but because it's so hot and dry this year the sand this year is like powder and everyone sinks leaving deep ruts.
NC is starting to look like a sweet place to go on vacation. Nice beach

The sand in NC is about the closest place for us in Virginia to go 4wheeling. Plus, there is an entire neighborhood on the beach at Corolla, NC, and the only way to get to it is by 4wheeling over the beach, over the dunes and through miles of sandy, winding off road roads. The locals have made some baja trails back in the neighborhoods (btw I use that term loosely, there are not that many houses except very close to the beach) and they are a blast!
Plus, there are wild horses that live on the beaches, so it's nice if you like wildlife as well.
Unfortunately, unless you have an aftermarket transmission cooler, you will be better off running in 4L in deep sand with your 07-11 JKU automatic. Design issues make it less about torque and speed, and more about preventing overheating. Also, make sure you switch off O/D.
Trying to save anyone some trouble. I know you can find this if you search for "High Oil Temp" or "aux trans cooler" or related topics, but I didn't find any of that until after I had problems. Just bought an 09 JKU Automatic. Found out that without an auxillary trans cooler on 07-11 JKU's, you are likely to overheat the trans in deep sand in 4H. With this setup, I now suggest 4L, O/D off, and air down to at least 15-20 psi.
