all of our trucks and trailers are either heavily lettered or fully wrapped. We find that we get far more calls from the wrapped vehicles with graphics than we do from the lettered ones. For the wrapped trailers we have our name&logo, website and phone number, and a brief general list f our services, along with graphics. We find with all of our vehicles that we get a better response to our website than phone calls. So we now have the website much larger than the phone number on everything. Also if you have a long or hard to remember domain, it is definitely worth it to purchase a shorter, easy to remember domain to link to your site.
Another thing we do on our enclosed is we have a section that has studs poking out. We have a number of different sheet metal panels that we mount to the trailers, each one has graphics and info for specific times of year.
Why do people not respect us as they do other tradesmen? Because every Tom, Dick, and Harry doesn't think he can be a plumber or electrician!
