pismo beach sand with wd bars and airbags. few questions.

i usually never unhook my bars unless i am going down some dirt roads with some major ditches. I know alot of my buddies unhook at the dunes (glamis) but we usually camp off the wash road so i dont unhook..never been to pismo but it looks like theres some elevation changes for sure, so as above unhook, air down. i run about 50-55lbs of air and then load the trailer so i get a bit more when you adjust for the trailer weight. Not only do the WD bars help with weight, they also help with sway when you run the hwy.
