I don't care for the heat but can deal with it. My wife is another story altogether though. She has a ton of health issues but the one that causes a lot of issues with the heat is a myocardial bridge so going into the heat causes elevated blood pressure which makes her feel as if she is having a heart attack. I have to do my best to make sure I precool the vehicle before we go somewhere as well as do my best to make sure that she can head straight inside and that wherever we are has decent AC. Also carry the instant cold packs and have had a few times where we have had to improvise ice packs with a couple of the plastic grocery style bags so she can try and cool her core down a bit.
Next year I am planning on pulling a vacuum on the AC system and recharging it with a different refrigerant. 134a just doesn't cut it when it's above 95 degrees. Heard the envirosafe stuff is supposed to work more like R12. It's fairly cheap so if it's not a big deal to try it out.
I did pretty well and fished through the whole summer last year, but this summer is kicking my butt! Still haven't figured out how to mount a swamp cooler in the bass boat.
