Dave,
For a couple of years we had a Herzog Explorer Touring - basically a self-supporting motorhome type awning, but adjusted at the factory so that it's a perfect match for the Eriba Touring caravans.
So what's it like?
Good points: Quick and easy to erect - just like putting up a big umbrella, the knuckle joints are good, strong storm proof poles, plenty of space...
Other points: Dark blue tent fabric is a bit claustrophobic on a winter's day, modern light-weight tent fabric on a rainy day is just like a wet shower curtain...
The images show two steps in the erection process - and just a few seconds apart - once the "knuckles" had been clicked...
Ultimately after several years use, we sold our Herzog and replaced it with a Dutch Fortex Aronde.
