Personally, With all my experience with vehicle lettering is that NOBODY gets it. My current van is simply lettered, but to tell you the truth i think next time around im just going to have my logo done,number and website on the area where your logo is and on the rear and call it a day.

I really like yours, simple & catchy! if people cant understand your logo and the icons do you really want them as your customer? keep it simple, have your website span the width of the icons and call it good.

Sweet looking graphics/logo!
