The Costco in Arvada, CO, at I-70 and Wadsworth, has 45 quart Pelican Elite coolers for $199. They appear to be pretty beefy, claim to be 7-10 day coolers, and they go for $350 on the websites I have seen. Take a look.
The Costco at I-25 and Hwy 7 (Lafayette exit) has the 95 quart cooler for $299. Not sure it's quite the size I'm looking for, or if the fit is going to work for my rig. But a beefy looking cooler, for sure.
