Mule Day Champion

Even though I always had the bigger sleepers, I always thought these looked so cool.
The small flat top box seems to accentuate the hood and stacks.
I travel light nowadays. I don't travel with a bunch of toys and only out 3-4 nights per week.
This would be ideal. Plus I like to sleep in little cozy places.

 

Here is a guy sleeping in an actual coffin. I found that looking for something else.

I have heard of trucks way before my time, like the 40s or 50s that had a sleeper tube with a hatch in the floorboard and the tube was parallel with the engine.
I have never seen one, but I think that is where the coffin phrase came from.
