How to rig a hammock in a sleeper

A common complaint among team drivers is the inability to sleep in a moving truck. Sleeping in the top bunk is impossible because it shakes so violently, and the bottom bunk isn't much better.

If anyone has successfully rigged up a hammock system to reduce or eliminate motion I'd like to see pictures of how you did it. I'm trying to figure out a system of using eye bolts and carabiners to rig up the hammock, perhaps with bungies to act as shock absorbers. Carabiners would allow you to install the hammock when the truck is moving, and quickly take it down when you have the luxury of sleeping on the bunk if the truck isn't moving.

In hotter weather a net hammock would also give anyone (solo or team) a better way to sleep with complete ventilation around your body, without having to resort to running an APU or idling to keep the air conditioning on. In colder weather you can stay warm by wrapping a sleeping bag around the hammock so you have insulation on the bottom side that isn't compressed under your body weight.

 

Instead of the standard bunk belt I would opt for wearing a harness like a rock climber, then clip that into an eye bolt on the back wall. I have experience sleeping in hammocks on big walls, like El Capitan in Yosemite. During our multi-day climbs we were never unroped until we summited. Big wall hammocks are single point suspension (usually with at least three anchor points equalized to one locking carabiner) and we had a separate set of anchors to secure the rope we had tied into our climbing harness. With a two point suspension hammock in a sleeper (like a navy hammock) it should be easy to simply rig a small rope to the back wall or ceiling with an eye bolt and clip that into a harness.

 

I would expect there will still be motion. However, hammocks have been used on sailing boats and navy vessels in order to reduce the motion from wave action. Even without shock absorbers there should be a significant reduction in violent motion, and it may turn that motion into something more calming and gentle than the sometimes painful motion of internal organs being shaken when the truck goes over bumps.
