Sorry I'm a little late to the thread here - pc problems.
 
Anyway there was a long discussion about these coolers on the RV-list a number of years ago. They rely on a couple of bent tabs on the end plates to keep the stack together. Some web surfing found some cases of failures. Scared me off.
 
The Setrab coolers look very similar but are better assembled. Lot of RV guys use them with good results.
 
The Fluidyne coolers are no comparison. They are very well built but heavy. I bought one but in the end didnt use it because I couldnt make it fit in the space available. I went direct to San Bernadino where they are made to see if I could get a custom one made to fit. Mistake. I mentioned it was for an airplane and that was the end of the discussion.
