Gull-wing windows are a great option for serious overlander or touring set ups – generally replacing the rear side windows with either solid or glass “gull-wing” opening windows. These give you side access into your rear storage area – often to access electrical boards, recovery gear, air compressors, kitchen equipment, food supplies, etc.
Gull-wing windows were an option on the Ineos Grenadier initially… but unfortunately were deleted somewhere in the development process.
Fortunately aftermarket suppliers are guaranteed to fill the void. Other vehicles have gull-wing aftermarket solutions from manufacturers such as Emuwing and Front Runner.
