I got my Long LPD 18,000 GVW coolers from amazon or ebay:

The coolers come with everything you need: The cooler, hoses, mounting brackets, hose clamps, nut and bolts for the mounts etc.
I used 2 coolers, one on each side in the nose in front of the condenser since I figured I could get them in without removing anything from the bottom front of the nose. If I was doing the install today I would use the biggest Long LPD cooler I could mount in the space or the Long Tru Cool Max if you can get it in place. My installation was done in 2009, 8 years ago, and still perfect, GP used as a DD all year round.
