If you do not want sand in your truck do not drive in the sand.

I do a lot of wheeling up here in the sand dunes. You will have sand coming out of your vents, seats, carpet, doors. Even with the truck sealed, windows up etc you still end up with sand every where.

Without the top you will have piles of sand in the back. That is uless you never spin-out climbing a dune <img src="/forums/images/graemlins/ignore.gif" alt="" />You will.

On the upside the bottom of your truck will be cleaner than it ever has been and your tires will look new.

Don't even try to run more than 10psi. It is amazing what tire pressure will do for you in the sand.

I will e-mail you some pics.
