When buying an awning for a camper van or a caravan one of the sizes quoted is the awning rail height which usually gives you the range of rail heights where the awning will fit.

Example

Fits awning rail heights between X and Y (measured in Metric)

So for information I have drawn up a list of awning rail heights for the touring range of vans as follows

puck 1.66 m

Puck L main awning rail 1.66 m if there is an extra rail above that on the door side for a standard size awning it is 1.8 m


Familia \ Triton \ Troll pre 2009 1.8m


Familia \ Triton \ Troll post 2009 1.86m

Eriba changed the height of the vans some time in 2009 to make them 60 mm taller hence the change in the rail height at that time.
