I am looking into getting a GPS system for use in my RV. I have a notebook computer and found a program that my son suggested. It is Microsoft Streets and Trips 2005 GPS Locator. It seems I can just hook it into my computer. I've read over some reviews that are saying great hardward but poor software. Has anyone heard of used this one, or does someone have a suggestion for any other GPS sytems that I could look into? One other thing I am looking into purchasing is an RV cover, does anyone have suggestions on the best cover for a 31' class C RV?
