That's what I have and will confirm Rick's assessment. They're fantastic. I see no downside after ~500 miles so far.
2000 M1088A1, 3126 in OE 330h tune, ~7' tall box on back, hwy gears, ECO hubs, somewhere around 25k pounds at this point.
For what it's worth, Rick sprayed Lizard Skin after checking out my rig. I don't know that it's
THE thing which makes mine so thermally manageable, but mine is similarly constructed to the 1079 box (steel frame, alu skin, a bit less thermal bridging), but maintains a very comfortable interior temp in direct sunlight. I went to great lengths to avoid thermal bridges with my rig and it is white, so it has a bit more going for it than a standard 1079 box, but the comparison to his rig when parked in the sun is night and day (yes, pun intended). It's not cheap, but I am of the opinion it is absolutely worth the money and effort.
It's also super easy to apply with their spray gun.
