THIS IS A ONE OF A KIND SPRINTER! It has a hybrid road AC system that automatically switches over to (wisper quiet) battery power when the engine is turned off. Heat is supplied by a Wabesto diesel fired hot water unit. All heat, ac, lights, pumps, tank heaters etc. are controlled by Firefly touch screens. Power is supplied by 11- 100 amp hr lithium ion batteries that can easly power everything for at least 2+ nights. Also a satellite dish that can accept DirecTV, Dish and Bell TV. Mobile cell booster, Apple TV and WIFI included. 2000 Inverter / 80 amp charging when connected to shore power. MaxAir ventilation with remote control provide plenty of ventilation. The sound system was upgraded with a JL Audio subwoffer and has the most incredable sound ever! Please contact me for a detailed list of features if interested.
