We purchased a 2017 34.4 about a year ago. We have enjoyed it very much. We had a few issues that we had fixed by Thor under warranty.
Our coach was represented as having the washer dryer connections but upon my inspection they had not completed the water or wiring connections. We had this completed under warranty and had a vent installed. Our coach will only handle a combo washer dryer. We plan to put one in next year.
One suggestion I would make is to consider the CHF (Cheap handling fix) and installing a Safe-T-Plus steering stabilizer. This combination has significantly improved the handling of our coach. You can find many posts about the CHF in this forum and others.
