Here is a screenshot of the combined US Topo maps:
Even if you don't want to load all the US Topo maps to your GPSr, having larger segments has other advantages. It takes MapSource a lot less time to build the mapset, building the mapset for the new combined US Topo maps only took 16 minutes, doing that for all of the original maps would take many hours. The combined maps for a given area will take up less memory than with the smaller map segments since there is some overhead involved with each segment. And you can even make changes to the features in the combined maps.
You can download the instructions from here.
The program can also be used with the new US Topo 2008 maps. If someone wants to donate a legal copy of US Topo 2008, then I'll generate the files needed to use with the tool.
