We just finished a trip and used Google Maps. After that trip I would certainly prefer something that let you input size of rv. Google took us down a few interesting roads that were really narrow. I'd also be interested in something for my motorcycle. I hate gravel roads and Google Maps removed the "avoid gravel roads" feature.
