update for any 385 owners... This is how we solved our heating issue somewhat..
We blanked off the under belly vent in the front storage, bought 2 different vent covers that can close completely for the bathroom and the front bedroom and bought a space heater for the back. The changes helped the mid cabin and the bedroom/bathroom but the back bunks just don't get heat because its too far from the furnace to get decent airflow so we have to use the space heater for the kids.
We ended up getting the 2nd air conditioner and we can get both to run on 30 amp as long as nothing else is running. I have also now heard they are replacing the main air conditioner due to noise issues, anyone able to confirm this?
The slides just needed adjusting so that problem went away. One thing that has come up in the last year and a bit is the wood trim on the top and sides of the slides seems to be very poorly attached. It almost seems like they didn't use enough nails... anyone else having this issue? On the same topic of durability the slide rails in the pantry have come off, anyone have any ideas on a different solution rather than the tiny screws they use?
