Compared to the Normal sleepers, these three Highline sleepers have more space for freedom of movement and more possibilities for storage in lockers above the windscreen. The extra height means there is standing room for all but the very tallest drivers.
So which should you choose?
P-series for low weight and high payload. There is sufficient space for a comfortable night out now and then.
G-series provides more space with the option of a second bed.
The R-series Highline combines ample space and comfort, and offers the possibility to specify the most powerful V8 engines.
