Having gone to Tucson in the middle of July (116F when we landed), I need to say it doesn't feel like much at all. Sure it's warm, but with the negative level of humidity it feels pretty decent. Here, the sweat pours off of you and you are well aware that you are losing water faster than you can drink it. In AZ.. I took a gallon jug of water to bed each night and woke up with an empty jug. Both suck...if given the choice I'd rather deal with the AZ lack of humidity.
Always had one of those wire holders, it's such a good design. Did you flip the engine mounts yet?
