yes, a tonneau cove helps a little, it decreases the amount of wind drag on your tailgate, but so does taking the tailgate off or just putting it down if youre going on a long trip

The previous answer given is technically incorrect. Usually tailgate down you increase the drag on a truck and will get worse mileage. A cover will actually improve you mileage a little but the weight of the cover may negate a portion of this. There are several studies cited online for this. Most places that talk about lowering the gate aren't basing it on science but on what they think is logical. Aerodynamics isn't about logic, it is a very complex science. Mythbusters actually tested this out, do a search on it.

Are guitar pickup covers important on a strat?

It depends on the pickup. If the pickup has adjustable poles or staggered poles, you need to have them exposed. If the pickup has flat poles (even for all 6 strings) you can put a cover over all of the pickup and get essentially the same sound as long as you adjust the height between the pickup and strings properly. Some like to take off the covers just to show the pickup, but some exposed pickups will get damaged without a cover. - MCE Guitars

How do you remove guitar pickup covers?

Desolder/break the welds that hold the cover to the pickup. *The pickup MUST be removed from the guitar for you to do this!* It requires a lot of heat to desolder the joints. It is easier to carefully cut them off with a exacto saw or a dremel cutoff disc. Heat the cover with a heat gun to soften the wax potting and gently remove the cover. You can reheat the pickup slightly to help remove the excess wax.
