In the 'did you know' on your website section: 6. Setting up your vehicle states:"TomTom maps can help to navigate large vehicles like trucks, buses or camper-vans".
I have a campervan 4.25 and find routing problems when I use a profile based on 'truck' as these are often prohibited on certain roads particularly if over 3.5t. Some towns or sections of road prohibit trucks completely.
A motorhome should not be classed as a truck!
Using the 'bus' profile is slightly better but still prevents a motorhome on certain roads where buses are certainly allowed.
Other satnav manufacturers offer versions specifically for caravans and motorhomes. However I do not know how well these perform.
Comments please.
