I live at 5800 feet elevation, camp at 9300 regularly and have driven over 12,000 ft. at times. You'll see your EGT's get a bit higher than usual but the PCM should be able to make the necessary adjustments for the altitude. Have any mods?

Yep, that's the key question. It would be good info for us if you let us know what modifications you've done to your truck, or if it's just bone stock.
If it's stock, you'll be fine unless you have some mechanical issues that exist already.
If it's modified, then you may or may not run into trouble depending on what you've done. For example, if you're one of those guys that threw on a higher horsepower chip or programmer and don't run any gauges, then you may be setting yourself up for a world of hurt.
#1 rule for modified trucks is to watch EGT's. That's especially important at higher altitudes, as the higher you go, the higher your exhaust temps will rise.

Heading to Orizaba, Mexico . . . road driving up until 8,500 feet. the other 5500 feet is off-road/ 4x4. I shouldn't have trouble with EGT's doing that should I?
Yeah, I'm a lame-o with a performance tow tune on the truck and no gauges.
I've had the gauges for as long as the tuner, just haven't taken the time to ever install them . . . and I would de-tune for the altitude except that 3 weeks ago my tuner was stolen from my truck here in Mexico, so I'm stuck in tuned-tow mode
To keep going on my sob story . . . the insurance won't cover my destroyed locks, the tuner, nor my DVD player. And last, but not least, I can't find WHERE in the user CP menu, to give myself a signature so that ya'll can know my mods and specifics. I'm pretty computer savvy, and I have looked for over an hour, multiple times, for where to change my signature. I know it is in the User CP area somewhere. Any help??
I have a 4 inch straight pipe out the back and a SB filter. I think I've got good enough air flow to keep the EGTs low since I only run the towing tune. However, I do understand that it is somewhat stupid to run without the gauges . . . how much time in hours am I looking to install them myself knowing absolutely nada? Working 12 hour shifts, pregnant wife, and a mountaineering trip for vacation . . . when does the truck get to have attention? After I melt it???

oh yeah . . . I do drive pretty conservatively as well. Conservative enough I sometimes wonder why I ever bought a tuner . . . pipe dreams that somehow I would get 25 mpg . . . and I'm still having trouble getting 15. Anyway, every now and again when I merge, I get on the gas for 3 or 4 seconds to avoid being run over by a Mexican 36-wheeler . . . but for the most part, I drive her nice and easy. Is that an excuse for the gauge disobedience?

AND . . . I'm not towing sleds up there. I'll be heading empty, a few axes, a rope, and a sleeping bag.

It's the cruising on the highway over mountain passes that really get EGT's up there.
