Checked tonight for codes using the mentioned procedure and was happy to see dashes "-" done! I bought this 2007 truck in August with 11k miles and have put 1,300 miles on it in a month. Most of it on the highway with my truck camper towing my Jeep. Did make a trip to Vegas empty to get the two recalls serviced at the closest dealer. So far loving it. I know you guys will be here for me when the first hick-up occurs!!!
I added a K&N in the stock box and that helped the empty mileage on the lio-meter from 14.7 to 16.6! My actual calculated mileage is about 1 mph less than the lio-meter.

Thanks for all the great information on the site.
