Taking features of the renowned Rally Air series, the Dometic Grande Air All Season 390 M Inflatable Motorhome Awning works just as well whether you’re touring for a few days or settling in for an extended stay. A substantial 3-meter depth living space is provided by the Grande Air All Season 390 M. You can expand this motorhome awning further with left or right-hand extensions, creating a setup that suits your specific needs.

Dometic's Air Frame system has earned its reputation through years of reliable performance. Single-point inflation simplifies setup; just one connection inflates the entire structure evenly using the included 2.2L pump. There are no multiple inflation points to manage or pressure balancing to worry about with this inflatable motorhome awning.

A dual-pitch roof system on the Grande Air All Season 390 M creates better headroom while actively shedding water and deflecting wind. This intelligent design prevents the common problems of water pooling and wind catch that affect simpler awning designs. For extended stays, this engineering makes a real difference to the long-term performance of the Dometic motorhome awning.

Weathershield All Season fabric represents some serious engineering. Dometic has tested this material in extreme conditions across different continents, from European downpours to Australian heat. The result is a breathable but incredibly robust fabric that maintains its integrity during extended use.

The Grande Air All Season 390 M's material maintains its strength and appearance even with prolonged sun exposure. Its UV-resistance makes it suitable for extended stays.

A dual keder system (5.5mm and 7mm) ensures compatibility of the Dometic Grande Air All Season 390 M with both traditional awning rails and modern cassette systems. This versatility means the Grande Air All Season 390 M works with your current motorhome and any future vehicle changes.

Apex ventilation maintains comfortable interior conditions by promoting air circulation and preventing condensation buildup. This becomes increasingly important during longer stays when the Dometic Grande Air All Season 390 M serves as a proper living space rather than a more temporary shelter.

The complete package for the Dometic Grande Air All Season 390 M includes: main awning, two side panels, two front panels, curtain set, storm straps, 2.2L pump, peg pack, manual, and two carry bags. A 39.4kg weight reflects substantial construction while remaining manageable for setup.
