I know that the poll is closed, yet have to comment a little bit. I think both need some work. Most have commented about design 1 and not much about the 2nd.
I think the second looks fine for the most part, yet somehow I remember the "wing" type of thing on a motorcycle logo, perhaps Victory or some new American motorcycle manufacturer. My suggestion is a bullbozer blade appearing as if it is pushing the logo forward instead of the wing thing on there. Just my thoughts.
Now for the 1st. The text needs some adjustment.
The one thing I think design 1 has that lacks in the 2nd design is the phone number. Is everybody that see the truck going to have to wait till they get home to look the number up in order to call them? I guess they could try to get them to pull over while going down the freeway. I think the best way is to provide a number on the graphic for potential customers to contact the business. Remember the guy wanted only the back of the window done, nothing on the sides so the back is the only way to have a phone number showing. A big part of advertising your business is for the customer to be able to contact you for work, right?
My choice #1 because the number is included. Needs work though.
