For the vast majority of applications where nights away from home are the norm, an R sleeper is likely to be a typical choice.
There are three variations: the top-of-the-range prestige Topline, the R Highline, and the R normal sleeper cab. All three offer two sleeping berths.
For those drivers who are more likely to complete daily schedules without frequent nights away from home, the P sleeper cab may be a preferred lower-cost option.
The cab has a lower profile with less headroom, though the driving position and associated ergonomics are of the same high standard as the R cabs. There is one sleeping berth.
