What were your data points again? Obviously they are essential for security.. Bill Ahrens W. A. Ahrens & Associates On May 27, 2014, at 8:24 AM, "Stephen North stephennrth@... [DSN_KLR650]" DSN_KLR650@yahoogroups.com> wrote:
YOU can believe what ever YOU want. And yes I DO believe my own data points taken in real time on my truck with my tonneau. (By the way, I'm not selling anything) but you saw it on TV?!!! It MUST be true for EVERYONE in ALL cases right? But let's get back to the point shall we? The difference in mileage is a trivial concern anyway up (or down in your case!) I was (trying) to answer the OP's original question (which I see you have made no attempt to contribute) listing several reasons why he might want to leave the tonneau on all the time. Tedious.

No improvement with bed cover. Believe what you want, you are obviously selling bed covers. Bill Ahrens W. A. Ahrens & Associates On May 26, 2014, at 7:30 AM, "Stephen North stephennrth@...

I would never attempt to make a blanket statement for all trucks and covers, accusing others of making false claims (based on my own individual results as you have) especially with regards to mileage as so many other factors can affect it. (Take your emergency brake off!) How heavy is the cover? Now that it's covered did you load the bed up with heavy tools and equipment? I wrote what MY results have been which I very carefully checked over multiple time periods keeping every factor the same. Other results may vary. The OP asked why he should leave his cover on all the time. That's just one reason. Keeping the bed dry and clean is another. Storage and security yet another. Mine lives on board. To me it's a no brainer.
