GENERATOR! As you can see in pics it's a Coleman 6500 running watts, 7500 max watts, Generator. 5gal. tank and runs on gasoline only. Have had it quite awhile and am moving, so needs to go. Runs perfect and always has. Havent used it much, just sat ready just in case. Ran it yearly testing out systems, then put it away for a rainy day. Tires were replaced cause old one eventually went flat. If listed then it's still available!
