I am wondering where people have been mounting the magnetometers for an EFIS in their Kitfoxs?

I am to wanting to get the Garmin G3X EFIS. The installation manual says to keep the magnetometer 8.2 feet from any steel structure over 2.2 lbs, which is impossible. They say the wing is best place, but you still have the lift struts that are steel and can't get that kind of distance.

It really doesn't matter what brand of EFIS you have, I am interested in hearing what others have found to be the best location for the magnetometer.
