I have a 2021 Nissan X-Trail and am looking at purchasing the Jayco Lark camper. Would this car would be able to tow this camper?

The Jayco Lark is available in two forms, the Touring (on-road model) and the Bushpack (designed for rougher roads and bush camping). Because of its higher ride-height and different construction (to handle rough tracks) the Bushpack weighs slightly more than the Touring with a tare weight of 1030kg versus 980kg. Of course, that’s the unladen weight and both versions of the Lark have a loading mass of 415kg (including an 80-litre water tank) that would take them, fully loaded, to a weight of 1445kg and 1395kg respectively.

The 2021 Nissan X-Trail, meanwhile, can legally tow a braked trailer up to 1500kg (1650kg for the diesel-engined version). So, yes, you can legally tow a fully-loaded Jayco lark with your vehicle.
