For me the ACA maps are at their best getting you into, through and out of dense urban areas safely and efficiently. Much of their bike shop/food information can better be found on a smart phone. I have never ridden across the US, but I would think their list of small town churches and other bike specific camping sites would be of great help. I find their elevation graphs to be less than great, but better than nothing. If you do a search of DOT websites, state by state, you may find there are free or low cost bike specific maps for entire states. Both Washington and Oregon offer them.
