Sometimes I get called to clean up a lot that another mulching contractor dropped a bomb on. The first thing I do, upon starting, is take my signs off my truck. The last thing I want is someone driving by and associating my company name with a mess. Thought it may not be common, instances like that make me glad I use magnets instead of wraps or vinyl. I also like to take my signs off occasionally to just drive around "incognito". I live in a rural area and you get to recognize every contractor's vehicle pretty quick with or without branding. We've all had jobs that we wished our signs weren't on our trucks.. if you haven't, you will.
