Best RV GPS for North America w/ Lifetime Map Upgrades

I've been using the Garmin RV 660LMT for three years and highly recommend it for travel in USA and Canada!! :B I don't know if it has enough detailed road information from Mexico to provide specialized routing in that country so beware. Check this link to compare the two Garmin RV specific GPS. You'll see that the RV 770LMT has a bigger screen and is more expensive but has fewer features than the RV 660LMT.

If you get into advance routing, be sure to download the FREE Garmin BaseCamp program onto your PC.
