FYI for those people with overheating issues with their VX

[VX KAT]

See if your mechanic has a scanguage or a temp guage that you can borrow for your test. If I wasn't using my scanguage this weekend, I'd send it to you. Sorry!

EDIT: Of course everything I've said is completely inaccurate if it's your thermostat that's causing the problem.

THANKS Tom!
We replaced the thermostat at same time new fan clutch etc...OEM of course.
Ironically, I just bought a SG2, but it hasn't arrived yet. I decided I want to know the engine temp/coolant temp, and we want to know how the tranny is handling towing on our other truck. (It claims to come with a tranny cooler, standard). Oh heck, who am I foolin', I just wanted one to play with and learn all kinds of new useless info!
I'm running out of 100+ degree days, so I decided to try it now anyway.

Boiling down the many words to few:

Drive it like you always drive it. It sounds like your trip will be challenging enough without trying to put extra strain on the cooling system.

Best o' luck & let us know how it turns out.
