I installed my heater when I bought mine last spring. It's the standard heater made by Curtis that was being sold at that time. If you're handy with tools, it's easy to install yourself. It comes with pretty good destructions that show how it's done. What followsapplies only if they still offer the same heater. </P>
Give up on the idea of keeping the cup holder unless they mount it so low that it'll be in the way of your left foot. That's reason one. Two: There is not enough room it "reduct" the flow out of the top of the heater. It's too close to the bottom of the cup holder. In fact, it would be flush with it. Your "frosty" would be luke warm by the second sip. Three: You'll need all the openings coming out of that little dude that you can get. I looked at the feasability of putting holes, "outlets", on the side facing the passenger. It's possible, but there's very little room there. Four: Once you feel that heat blowing out of where your Coke used to be onto your freezing hand, you'll forget that it was ever there. Five: It has a swivel outlet that you can turn toward the windshield to get your breath off of it. </P>
We live in the extreme northwest corner of NC. I used mine yesterday for the first time to move snow off our gravel driveway. It's about 1900 feet down a very steep hill. We had only about 2 to 3 inches but once you drive on it without getting as much off first, it gets packed and turns to ice. And stays for days if it dosen't get above freezing. Even if it does, where it's shady, it stays for way too long. You see why I want to get it off as soon as it falls no matter how little comes down. </P>
The RTV did me proud. I have the Curtis snow blade sold by the Kubota dealers. I also have the soft cab. When I used to do this with my Kubota 3410 tractor, I had to push snow down the hill, and come back up and push the other side, going down hill. Yesterday, after pushing going down hill, in two wheel drive (I forgot), I switched to 4WDand pushed the snow off coming UP hill. Granted, not much snow was on the ground, but the RTV acted like it was nothing. I was finished in less than 30 minutes. That was actually dissappointing. I put a considerable amount of money into this and I want a little more time in there. It's fun. If you're going to use your RTV in the cold, you'll never regret getting that heater. I had my coat and gloves off after just a minute. Hope this helps. Rog</P>
