We have the Garmin 760 also and love it. We went from PA to FL to New Orleans and back to PA again. We traveled with another couple that had a regular car Garmin (older, yet accurate to our travel). Their Garmin took them different ways from ours, but all in all, we probably made better time. It did avoid places with low overhangs and low lying trees, where theirs did not. You plug in the height and length of your TT. The one thing it does not have (and I think they are coming out with it soon) is propane/hazardous restrictions. We knew about the Fort McHenry Tunnel in Baltimore and luckily, that was the only one on our route. The 760 also alerts you to traffic, changes in speed limits, tells you which lane you should be in, etc. I highly recommend this one. Problem... we got the one with the camera and our TT is prewired for Furrion. Trying to figure out how to get our camera to installed.
EDIT: I forgot to add the very best part. Garmin is constantly sending updates, so it is ALWAYS UP TO DATE!!! We have updated about four times since we purchased it in September.
