Just purchased a 2015 Seneca HJ. I did a trip with a 20' enclosed trailer to Road America in Wisconsin the day after I took delivery!!!! Put around 1000 miles on it and really like it except it is a rattle box from the drivers seat. Back at the dealer for some punch-out items
As a fellow HJ owner interested in what you have to correct. They are a great driving rig. We still have a few things to correct or figure out such as low volume from front TV. We did not get a complete set of manuals so not sure if it is because the speakers are inside the cabinet or operator error.
