Thanks Santiam!
I know you have to have an off-road sticker and flag for driving on the sand dunes.
I have an off-road sticker and flag on my sandrail, and my buddy has the same on his Jeep.
My truck is a Tacoma 4X4 TRD, w/airlock rear end, so I think it will do OK on firm sand.
Best to just buy the sticker, and mount a flag, to make sure.
I have an Oregon off-road license.
Can't WAIT to get back over and give it another try!
