Awning Size Guide


The Grande Air All Season awning has the Multi Height System that allows the awning to be used on caravans but also 95% of motorhomes. The height range is now from 235cm to 265cm plus with the double Keder means that it will work on the rails of a caravan and a motorhome without any complications.

If you need extra space you can add extensions(Special Offer) or an annex that can be used for storage or extra sleeping areas.

All Dometic inflatable awnings feature a single inflation point, multi height system and apex ventilation. Storm straps and manual pump are included as standard with an electric pump option available.

The use of optional limpets or rear upright legs help create a better seal with the vehicle and reduce draughts. A veranda pole can be used on the front windows for increased ventilation on hot days.

How to measure for the size of your awning

  1. 1. Ensure your caravan is on a level standing.
