We have been using a 7710 (father, or maybe grandfather to the 7735) for almost three years and find it quite satisfactory. Like others said, turn off the things you do not need, but leave the RV Warnings in place.
I can lay out a route exactly as I want it on the GS website trip planner. Use drag and drop to set waypoints for precisely the road segments I want to use, and then export it to the GPS
Both the trip planner and the GPS unit itself will pop up warnings for low clearance, road construction, narrow roads, propane restrictions, etc. The GPS unit can be set to avoid tolls, U-turns, dirt roads, and several other things.
It will also tell you where the nearest Wal-Mart is!
As I said, we have had no problems with it. (I did purchase "Lifetime Maps", but I think that may now be included.)
