gps for rv's

[msman]

hey all

just wondering if on your travels anyone has come across a gps which is suitable for rv's/trucks i.e. one which avoids low bridges and weight limtied roads.
an elderly lady i work with is retiring soon and is going on a around australia trip in a rather high rv and asked me today if a gps is available for this purpose.

i have seen a binetone carrera with this feature but they offer poor reliability.

cheers

i have a kogan unit and it allows settings for pedestrians, bikes, motorbikes, cars and trucks. im not sure what the differences are as ive never been through them all..

hows it been?
would you recomend it to your mother??

cheers

it is a great unit at a great price, i would reccomend it as it has so many features (mp3, photo album etc)the only downside is that it dosent know the difference between dirt and tarred roads. i compared it with a navman and i think the kogan was better and at about a third of the price..
