This vehicle has ceiling Air Conditioning which runs on generator while driving and on campsite power or generator when parked. It does not have dash AC so ask more about this if your trip includes hot weather. Generator runs on top 3/4 of truck gas tank, it does not run on the last 1/4 of gas tank. This vehicle does not have ABS system. Browse the Add-ons and select things like delivery, kit, awning, service for water/waste and propane or truck fuel etc for locations without hookups or other unique generator needs. Mileage over any included or discounted prepaid, will be at a higher rate at return, .35 cents per mile or see rate sheet. I'm always happy to answer questions.
