Some of the new changes for 2017...
...
12' Dometic Power Awning with remote.
Dometic 9500 Power Case Awning
This design is typically found on high-end Class A motorhomes and custom RVs and specialty vehicles. The biggest one I've seen was on the side of an IndyCar team transporter, running most of the length of the trailer and extending over the entire width of the service area beside it - at least 3 metres (10 feet).
... does the new awning have metal supports to either the body or ground for better support in reasonable winds or light rain?
...
is the previous awning with metal supports still going to be available?
The supports for the new awning
are metal - they're just horizontal, rather than vertical or angled down from the outer edge of the awning to the bottom of the trailer.
Clueless about awnings - how does it stay out like that without any supports?
The supporting arms are not immediately apparent, but you can see them under the fabric. They fold horizontally, instead of telescoping or folding down. Dometic's online descriptions are lousy, but the beginning of the
video posted by Camping World shows the arms pretty clearly.
The arms need to be really substantial, as would any beam only a few centimetres (inches) high reaching out that far; the 16-foot version of this awning (assuming I've found the right one) weighs 46 kg (102 lb)... this one is shorter and so lighter, but it's still a substantial chunk of hardware... presumably at least 36 kg or 78 lb.
The awning was something we were really excited about. Ease of use! It has an 8' extension with no need for extra arms. It has a built in wind sensor that will automatically close the awning if it senses too much wind. It is most susceptible to wind when fully extended, however you can open it only as much as needed.
This is certainly a major change! Reace, the mounting recess is apparent, but what did you need to go in the body structure to handle the forces on the awning mounting area? The weight of the awning (and vertical loads due to winds) multiplied by the long lever arm of the awning extension is a lot of torque. I've never seen this type of awning on a fiberglass shell structure like this.
The previous awning design required bending of the awning arms to follow the curved side of the trailer. Some other awning designs were impractical due to that curve. It's interesting that an awning that is not affected by curved walls is introduced at the same time as flat trailer sides.
