I'm buying decals for my truck. I'll have all my info (Logo, name, email, phone) on the sides, just fine. The back is where things get tricky. I plan to install a headache rack on my truck for practical purposes, so the rear windshield is not an option. That being said, I eventually plan to put a 12" x 36" decal on the tailgate with all my info. However, this will not be visible when I'm pulling a trailer. I intend to purchase a 36" x 48" sign to attach to my trailer gate. (I've checked. People do it.) I'm on a budget, so in the short run it'll either be the tailgate decal or the sign. Assuming a few months in between, which should I buy first? For the time being, I'll probably be driving more with the trailer than without, but the image presented (and size presented) are things I'm considering.
