Sand tire wheels

I need some help with figuring out what wheel offset to go with on my sand tires. I read the shock therapy thread about adding offset to the front creating bump stear ect. I was told the sand is different than the desert.

I'm looking at dwt sectors. 14x7 4+4 front and 14x8 5x5 rear. I was told staggered offset was best. Stock suspension xpt4. 30x13 skats front and rear. Thank you for your help.
