The Westfield Neptune 2.0 is designed to fit motorhomes and campervans with an awning rail height between 240 cm and 320 cm. Available with 4 Zip In connection Tunnels, in multiple height options to ensure a snug and secure fit for a wide range of vehicle types.
Yes, it’s built for all-season touring. The awning uses HydroTech® Cotton-Touch fabric with a 10,000 mm waterproof rating and UV protection, plus built-in ventilation to reduce condensation. It’s ideal for both sunny summer trips and rainy UK getaways.
Very easy! The Neptune 2.0 features an Advanced Air System with single-point inflation, allowing you to fully inflate the awning in just a few minutes using the included high-pressure pump. No poles are required, making setup quick and stress-free.
A motorhome air awning uses inflatable beams (instead of metal poles) to create structure. These beams are pumped up manually or with an electric pump, making setup faster and easier than traditional poled awnings. They’re ideal for touring and short stays due to their convenience.
Yes. Most modern air awnings are made with high-denier waterproof fabrics and reinforced seams. Brands like Westfield, Camptech & Dometic offer models with hydrostatic head ratings of 3000mm or more, making them suitable for rain and wind typical of UK campsites.
Choose a drive away awning if you want flexibility to leave your pitch and return without packing up. These freestanding units are ideal for touring. Fixed awnings are better for longer stays and offer more stability but require detachment if you move the motorhome.
Fitment depends on your vehicle’s height and the awning’s connection system. Most awnings list a compatible height range (e.g. 235–250cm). Common attachment methods include keder rails, straps, and magnetic kits. Always check compatibility before buying — or use our Stand Art Fitment Guarantee for peace of mind.
Inflatable awnings are quicker to pitch, lighter, and easier to store. They’re great for solo travellers or frequent movers. Poled awnings may offer more rigidity and are often more budget-friendly. Some users prefer poled models for extended stays or harsh weather.
