the finest coolers we have found are the Setrab coolers, they drop the temp
about 40F for the single, and 60 for a double.

The mesa cooler are not nearly as efficient, nor space friendly, but they
are cheaper. If you are keeping the van, a Setrab is the way to go, no
question.

Since it's brought up on the list; we'll give free shipping on Setrab
coolers thru the end of June.
