The resistor fix is so easy to do at home for next to nothing, I could not make myself buy $100 resistor. I opted for S-VCM to have some flexibility in the operation and still be able to see the temperature increase if truck starts to overheat.Glad to hear some ppl are trying out the S-VCM approach. I'm also interested in what he came up especially since it appears that he is using the battery power to help make measurements. My only drawback is how low his rating is on ebay. I like to see more results from the product is being used and how he has refined it for the scenarios he hasn't encountered yet.
