Many extras included, like extra cameras to see traffic rear and each side. New 5 KW Onan generator that runs on LP. Allows use of "house A/C" running down the road. The diesel engine runs very well; and can be driven fast to keep up with traffic. No need to use DEF in this vehicle. Nearly new tires all around. Gets very good fuel mileage. Operates and runs and drives very well. I am selling only due to my advancing age and not using it enough to justify owning it.
