Well, I have towed for about 1000 miles on this trip so far. The crank sensor has worked well. I recorded the highest MPG I have ever recorded with this truck when pulling my 5ver. I recorded 9. 5 MPG on a 260 mile pull, cruise locked at 65 MPH, 90 degrees, and about 4000 foot elevation. For me that was remarkable. Tomorrow I leave for Texas, about a 300 mile pull. Out of curiousity I want to disconnect the EZ and just run with the crank sensor. More to come as the miles go by... ... ... :-laf
