Aerial View Maps - Need help selecting GPS unit and good maps (topo, etc) for off-road/dirt road navigation.?

Need help selecting GPS unit and good maps (topo, etc) for off-road/dirt road navigation.?

I've been doing lots of research but I keep finding either outdated or conflicting info. What I need is a GPS that comes with, or will allow me to load maps that show old, barely used off road vehicle trails, hiking trails, and forest service roads. I'd prefer to have the option to actually navigate with these maps, or at least to add my own way points along selected routes so I can track. ALSO- It'd be nice if I could use the GPS for standard highway/city navigation and POI finding. So, in summary my questions are: Is it best to buy two separate units, like a nuvi AND something like the garmin colorado, or can I load decent navigable topos onto a nuvi and have a single unit? What are the implications of such a choice? Do the Garmin Colorado/Oregon/Dakota units have stronger reception than nuvis in canyons, etc, or are they just "more rugged"? Please advise a good approach. Thanks!!
