We've been in our 2022 3855BR since June. I've been working full time from the office and can say that room is always closer to the outside temp than anywhere else in the RV. Keep a fan to blow in extra AC in the summer, and a radient heater to provide extra warmth in the winter. Have the windows open right now.
Build quality on the unit hasn't been great, but no major issues so far other than a leak in the outdoor kitchen that soaked the subfloor and caused mold. We are in the warranty repair process right now to get it fixed. The issues have been things like one wall was made too tall, and there is a gap between the wall and the ceiling between the bedroom and bathroom. There is a gap between the wall and the stairs. One of the steps is not level. Things like that.
We love the floor plan. The unit tows great. I do wish it had about 1000 lbs more cargo capacity to actually use it fully. We are pretty close to max weight with all the tanks empty.
We replaced the couch in the office with filing cabinets to make it more functional for us. We also pulled the table out and put in cabinets for extra drawer space. Ordered a counter top that matches the island to put on the cabinets so it looks great in the space. We also had the third AC installed as anytime it got over 85, two just didn't keep up.
