I can't tell if this is a problem with a 4 runner 4WD, but on my '95 4WD the lower hose connection is behind the A/C hardline and I can't close the hood. Revain's product finder told me it would be compatible with my truck, but it isn't. I'm sure it's a great cooler, but it needs to be made clear that it's not for 4Runners and pickups. on Revain but listed as not suitable for 4runner for some reason.
