Modern satnav

We've got the Avtex Garmin tourer in which the unit's dimensions are entered. It’s also got the apps for both clubs.

Seems to work but I don’t think it’s worth the money and employing a hefty dose of common sense and using a map in conjunction with the satnav would be my first choice. Note that you still need to follow the club's written directions for the final approach to sites as entering the site postcode will not necessarily take you over the recommended towing route or to the site entrance.

Ive gone back to a HGV bridge map ,as i got fed up with being told to turn left ,,when it was the next one !! 

Don’t waste your money unless you want bells & whistles like voice control, traffic info, phone connectivity etc. They all seem to use the same road information database, so you’re just as likely to get into a tight situation as you would using a basic sat nav if the source data doesn’t recognise it’s a single track road with few passing places and a medieval narrow bridge with height & weight restriction - it will happen!  

I don't know what sat navs you use SSB but I have found some sat navs to be much better than you state. Truck sat navs seem to be loaded with much more data than those designed for car and caravan use.

My advice if you want better reliability from a sat nav and have a larger vehicle, get a truck sat nav.

Maybe so, but my point is there are limited map/geographical data sources - Tele Atlas (TomTom) and Here/Navteq (Garmin).  So, if you pay £80 or £400 for your TomTom device it’s using the same underlying data source, and sometimes it lets the £80 and £400 customer down in exactly the same way. 

I live in Cornwall and every year encounter lots of caravans and large motorhomes in places they really ought not to be, often blocking the smaller local routes. Being a motorhomer I have some sympathy for their plight so often end up helping them out of their predicament. The thing I most often hear is “the sat nav shouldn’t have taken me this way”. In most cases they’d blindly followed the sat nav, ignored umpteen ominous signs and had simply failed to ‘read the road’. A bit of preparation and common sense would have spared them the stress.

The second photo are the worst offenders of all, hired motorhomes!

As for truck sat navs we have at least one lorry a week having to reverse up our cul de sac when they arrive to find a  12 foot railway bridge between them and the factory after paying hundreds of pounds for their sat navs and even more upset when given the details of the detour to get there. Funny how they put more faith in the sat nav than the flashing low bridge signs 

Tell me about it, 0001!  It’s almost a daily occurrence here. They ignore the direction signs and find themselves faced with a low bridge. Time and time again the road is blocked while a lorry has to reverse. What has happened to using eyes and common sense😤

My favourite, SB. In Meva. 

If anybody is thinking of buying a lorry sat nav, don’t buy the same one as B&Q use!
