Hi Chris,
Longtime no see. I know several people who have them, and the general consesus is that they add to the rigs stability. Fuel economy is still hotly debated, some say1-2 others say none at all. Considering the price, I am wingless at the moment because all of my trips are usually short < 500 mi.
I'll be at the Breakfast House Aug 2, try and come. Can't make it this weekend.
