Since we don't have the electronic AC controls, our multi-meter gauge displays the temp as well. I believe that if you have the digital AC controls then that displays outside temp. I still don't know what the "Up" and "Down" buttons are for on our multi-meter.
Third party hood protectors are a tough proposition. We ended up having to buy a Kia brand one because we couldn't find any other. I will say that I don't really like how the Kia hood deflector is mounted, but we didn't have much choice. It was simple enough if you know how to turn a wrench and which end of a screwdriver to hold, but I don't like the little metal and plastic clips it uses.
You can get a Hidden Hitch brand class III hitch for your truck for around $125.00 (2" square receiver, 5000lbs towing capacity), but you will have to spend extra for the wiring connector. You can't just hook the trailer directly into the factory harness under the right rear corner. It doesn't carry enough voltage or can handle enough amps to power your trailer lights. There are several aftermarket adapters which will work for around $50 which will have their own dedicated power line, then you can use the factory wiring plug to provide the necessary signal to activate the trailer lights without pulling too much power from it. The whole job took about an hour to install. Last year we spent exactly $103.99 (plus $18.35 S/H and $7.28 local tax. Total = 129.62) from a place on the internet located here in Orlando called BAGE Co.

Follow the links for Round Tube hitches. I just looked and the price has gone up to $120.43.
$29k isn't too bad for a fully loaded Sorento in NY, I guess.
