Infrared Thermometer, laser targeting

[pgchin]

FWIW,
I'd suggest if you do not already have one, you might put this on your wish list. Comes in handy for any "situation". We stop every 2-3 hours for the dogs, I just ping the tires, tranny, radiator, engine block, differential,etc., takes 5 minutes and can give you a heads up to potential issues. The laser makes pointing easy as you want to get the actual outside shoulder of the tire(the hottest point).
You can find many uses at home as well as in the bus, checking ac and heat temps, skin temp (bus) etc........

PS any model or vendor will do, this URL is just an example. I actually have this one and it's 7 years old, works great!
