Experience with Portable GPS Units?

[Jeff Miller]

The gps will not receive through the steel skin.

It therefore will see sky through the windshield and some thorough the
side glass. When you are in a valley or road cut into mountains, you
will need enough "birds" above to ahead of the coach to maintain
coverage. Same deal in a city around buildings.
Having my GPS lose coverage temporarily in some conditions where the
terrain is blocking some of the available birds, I added an external
antenna to my Garmin GPS with great results. I wouldn't go back to not
having a 360degree view of the sky, much more reliable.
