I was away last weekend on a canoe trip, most of the roads were dirt or logging. On the dirt roads you could get going pretty quick, and there was some pretty good washboard sections. I noticed after my cab had a couple marks from the box contacting it. Is this common?

Short answer, yes.

Check out this video originally posted by member Andrewvk. It shows bed movements of various trucks. I don't remember if there is contact but you'll get the idea.

Fairly common. I have several dings in the back of my cab from the bed making contact. Usually on high speed jaunts across bumpy terrain.

My back wall on the box broke
So it rubs against the cab

If you are driving on rough roads that causes bed/cab contact, you are probably driving too fast.

I was doing 60 KPH. That afternoon I was with my friend in his 2004 Chev, he was doing 120 and didn't even compare. I was pissed, felt like my truck was out of control. The posted speed limit was 80 kph.

Posted speed limits doesn't mean it is the safe speed.

The key to traveling over washboards quicker is to lower the air pressure in the tires.

That and drive faster. The faster you go, the smoother it gets. Right up until the point where sh!t starts flying off >
But seriously, there's a point where your suspension oscillations match (or cancel out if you will) the washboard frequency. That's when it smooths out the most. Same deal as moto X'ers and desert racers flying through whoops but on a smaller scale. You have to find the pace where your tires stay on top of the bumps instead of falling into the valleys between them.
