Tasmania Trail with bob trailer

Hi all,
I am interested in doing the Tasmania Trail on mountain bikes with my 12 year old son. We intend to break the trip into the 3 map stages. I intend to tow a bob trailer along with us and was wondering if the track was suitable to do this and has anyone else done the trail with the bob trailer.
Also we intend to buy a copy of the book online, and was wondering if the track is well sign posted at the moment, as I have re
ad on an earlier post that it wasn,t. Would a GPS be advisable and does the book give any co-ordinates.
Any help or advice woukd be greatly appreciated as this is our first adventure.
