The Mercedes Sprinter diesel chassis is the headline here, giving the Sunseeker 2400Q MBS road manners that owners rave about. Drivers consistently describe it as easy and comfortable to pilot, which is a real advantage in a Class C that still fits a mid-bunk layout and a full bath into 25 feet. Forest River has done a solid job opening up the floorplan so the interior feels more spacious than the length suggests. As with most Sunseeker models, fit-and-finish can vary unit to unit, so a thorough pre-delivery inspection is worth the time.
