What is better for deep soft sand? 4HI or 4LOW. And what tire pressure? I used 4HI and 16 lbs last time but I felt like I was bogging down a bit especially going from rut to rut. I am also using standard passenger tires (versus the knobby types). The bogging down may have been my fault as I was very nervous so I may not have been accelerating properly or staying in the right ruts. This was my first go at off road and the ruts were huge leading me to believe the sand was very deep.
When off-roading in sand, mud, etc. most use 4-LO. However, often when running on sand such as on the beach you like to get up to speed - and 4-LO should only run up to about 15mph. Any faster than that and you're turning some serious RPM's.
Work on your technique a bit more. As you said it could be the acceleration and use of the throttle that caused the Jeep to bog down vs being in the correct TC range.
