There a loads of POI's in RVTW, but you do have to expand the menus to see them all. You can also take advantage of location sensitive search. In other words, if you are zoomed in area, and you go to the search bar on top and type: Winery, for example, Places of Interest will show up in that search window. The farther you zoom out, the more options. Works fantastic.
As to the Avoid Highways....yep, that's what it's going to do. Expect a much, much longer an obscure route if you are going to avoid highways. Best bet is to leave that button off, and manually control your route with custom stops or points of interest to take you in other directions.
As to road colors, generally speaking, the lighter the color, the smaller the road. Red = Interstate, Yellow = Highway, Gray = Rural or Farm Road or worse.
