Amen Brother!Why do people ask for input and then ignore others advise. Even at 1" low res. we can still tell that the lettering will be uneffective. If the lettering on your truck will not read well why would a customer think that their lettering would turn out any better. Stick with one idea ( design) and establish it. By doing this for yourself it will make it easier to sell image to your customer. Practice what you sell. I have seen to many sign shop trucks in my area that have unreadable lettering..... which for me is a good thing.
