Lay down in the bed and nobody will see.

Have you ever been in the back of a pickup? This would be incredibly uncomfortable at best and is likely to cause a concussion or worse.

I have. I had a pillow. Went about 45 miles. I don't recommend it.

Edit: The ride really wasn't so bad, but it wasn't exactly comfortable, and it was a bit awkward. I recommend riding in a factory installed seat with a seat belt. For safety.
