It sounds like (sorry about that
) there is little sound tranmitted through the truck bed, the side walls, or the cover. You might be able to build several baffles to stand across the bed of the truck between the generators and the tailgate. Each of them could stand on edge from the truck bed up to the cover and extend maybe 3/4 of the way across with a foot or so between each baffle. The openings could be staggered from side to side so there would be no direct opening from the generators to the open air. A fan or two might be necessary to keep enough air flow for combustion and cooling.
It seems this would be making your truck bed into a muffler. It may seem odd (I have never heard of it being done before), but it might be easier to try than building a box.
There are sound absorbing products out there (Homasote is one brand) that aren't very expensive, easy to work with and may make excellent baffles.
