Default How much power for APRS?

So, I'm toying with the idea of building a stand-alone APRS system for my truck. The loose concept I'm thinking about would be to have a TinyTrak 4 and a dedicated 2m radio hidden behind the dash. The GPS receiver would be mounted on the dash. Eventually (but not anytime soon) I'd probably hook up something like an AVMap for a display. I am thinking I'll power the whole thing via a splice from the cig lighter so it'll be on anytime the ignition is on (but I'll put in a kill switch in case I am someplace that I don't want anyone to know about).

So, my question is… Will a 5W radio (with a good external antenna) be enough to reach digipeaters when I'm in remote areas?
