Depending on the road we are on, we sometimes have trouble identifying the make of the RV coming at us, those interstates sometimes are seperated by a LOT of median!
So, unless those numbers are HUGE, in many cases they are not going to be read while tooling down the highways and byways, at least by Countryguy and his Mrs.
Have seen the numbers in the middle of the back, the nose cone up high in the middle and all over trucks and signs, very creative batch of folks here at the MOC.
Be sure to post a photo of your finished product!
