My main complaint with our 465 is that in truck mode it will avoid any road that a truck is restricted from using as it should. The problem is many of these restrictions have nothing to do with size but with noise or other items which do not affect RVs. I find using a truck atlas or the web site for overhead clearances in coordination with just about any GPS will work as well as the 465 since you still have to research the route to see why it is taking you down back roads 20 miles out of the way!
Once they get the bugs out of the new Rand-McNally RVND gps that is specifically programmed for RVS with camping POIs, I think I will have to give it a try.

Can the Dexl 560 switch between truck (rv) and auto mode?
Yes. But note, Truck and RV modes are listed separately.
The Dezl 560 has 4 modes: Auto, Truck, RV, and Pedestrian.
We've only used ours for two outings, one being this week end. I do not know how it routes differently for truck and RV, I haven't had it long enough to find a difference. As far as car and RV, I know that the routes are different. I looked at both of our trips both ways - can and RV. Both times, for RV it chose to two two legs on interstate highways instead of taking the diagonal two-lane road it suggested for autos.
I had one until it was stolen out of my truck, I admit my fault, forgot to lock the truck in my own driveway, and was happy with it, but replaced it with the dezl, and so far like it very much, especially the actual pics of off ramps and other selective modes.
I did consider the RM but at the time (Nov '11) still seemed buggy to me.
I still haven't done a truck/rv comparison yet.
Having said that, any GPS is just so rarely off, that they are not 100% reliable.
