Launched at the latest NEC show to no little fanfare, the Lunar Quasar 646 is the final, range-topping touch to what is already a pretty comprehensive line-up of Lunar Quasar caravans. Until now, the only six-berth in the range has been the single-axle 586, whose interior layout comprises parallel front settees, a side dinette that folds out into bunks, fixed bunks and an unusually spacious corner washroom that packs in a separate shower cubicle.

The 646 pretty much apes its smaller brother’s layout, but the extra inches afforded by the twin-axle chassis (1ft 3in of shipping length and 1ft 5in of interior, to be exact) opens up a larger kitchen and – crucially – longer lounge seats. All the beds are significantly roomier, too.

Sticking to the long-standing Lunar ethos, the Quasar 646 may be an imposing caravan, but its weights are commendably pared back. That said, sticklers for laden 85% matches will need to invest in a tow car weighing more than 1800kg, which is well into large SUV territory.
