I use Streets/maps for all my "preliminary routing". I can customize the "find nearby places", to include campgrounds, Etc. there is a menu to select what you want. It will calculate distance, costs. That gives me an idea. Then I use RV park review, to get an idea about the campground. Also, I try to find "places" after about 5 hours driving. Once the "plan" is determined, I still use the road atlas to verify. I don't think Streets/maps has "bridge height" info. That would be in the newer GPS units, altho would be costly. I found a TOM TOM on clearance,with up to date maps, for $78.00 no height info tho.
