Both Delorme Typo and Nat Geographic are good typo maps.  I use the both.  As well as the program Outdoor Navigator by Maptech.  It allows you to use Jpg picts and to download map ares.  Most of the typo maps will show trails.  Some maps only show hiking trails while others will show off road trails.  As far as just ATV trails you would have to download the gpx trails from websites and than overlay them using the typo map program.  Most typo map programs allow you to edit on the PC than download the map and overlays (trails and tracks) onto the gps unit.

I am trying to give you the link for free Garmin Topos but this site will not let me post anything that looks like a web link until I have made 5 post.  Never seen this before.  This is my third attempt to post this.

Go to xxx.gpsfiledepot.com

replace the x's with w's.  Maybe I outsmarted this site.
