Re: Ceiling Panels - 2023 T@b 320
Ok, I'm glad to hear the Factory helped. Taking a section out would probably be the only way to access that area. Keep us up to date on what you find, and some pictures of what it looks like above the interior ceiling would be very useful. As you saw in the other threads, this is not a very common occurence, so there isn't a lot to go on as far as repairs go.
Re: Alde Diagram for 2021 400/Bleed locations
I do not know for sure but my guess is that your configuration is normal for a 2020 and earlier model. They seem to have added bleeder features such as valves and tubes in later model years. My early production 2021 400 has all the bleeder valves mentioned in this thread but only has a bleeder tube on the location behind the bed and on the location behind the dinette wall by the door. We have no bleeder tube located under the sink. That one was added on the 2022 models or possibly late 2021. They will make running changes on occasion during a model year. If you wish to add a bleeder valve you can always do that. You'll just have to drain the system and get the appropriate hose and or bleeder valve. From my experience draining and refilling my system, I removed most of the air from the bleeder valve behind the bed and in the bathroom. Not much had collected in the other locations.
Re: Alde Diagram for 2021 400/Bleed locations
It is perhaps worth mentioning that my 2020 T@B 400 Boondock Lite (Build Date: 09/2019) does not have Alde bleeder valves in three of the above mentioned four locations.
My T@B does have a bleeder valve under the shower, but not in the other three locations in the diagram above. I removed panels in all three of these locations to gain access; no bleeder valves were found.
I have no idea if this is typical for 2020 T@B 400s. Do you know if this is typical?
Re: Ceiling Panels - 2023 T@b 320
I just saw your FB post on this, and the various comments about trailers from 2006 until today. We have seen the roof leak, but most of those issues happened at the edges of the aluminum sheet that makes up the roof.
We have also seen "delamination" of the various ceiling coverings over the years, usually from glues working loose, and the different ways the ceilings were covered.
The "seams" of the ceiling are covered up by those plastic looking covers extending from side to side of the ceiling. What exactly did you mean by "trim was removed"? The trim around the fan? Or the ceiling panels themselves? Did this dealer actually speak to the factory? Have you checked with NuCamp on how the panels on the ceiling could come off?
If there is a tiny leak (or was) in the caulk in the ceiling fan, just running a hose over it would not simulate the pressure of water while driving down the road at 60 MPH.
I think you have a basic good idea to try to get the ceiling panel off.
This is a search of the Forums for "sagging ceiling" that may give some clues here.
Re: Access "port" for Alde yellow flappers, T@B 400 . Done !
The nice thing about the 2019 400, a cargo door for access to the Alde area, no Nautilus.
Re: Access "port" for Alde yellow flappers, T@B 400 . Done !
This is a great idea. I didnt have the guts to cut the skin of the trailer so I took a different route. I cut an access hole in the deck below the mattress and above the valves. Unfortunately, that means we still have to tear apart the bed, but at least I no longer have to lift the whole plywood panel out to do a simple job. 
Re: Access "port" for Alde yellow flappers, T@B 400 . Done !
Thanks ! Yes, it was a bit of a nerves of steel kind of thing , lol . Was fairly confident in my measurements , and also had a trick up my sleeves with a little help from mother nature .BandB said:@B0atguy great work! We did that to access our 2022 320 Alde fluid reservoir. Great idea to install one for the yellow flapper, too, but I'm not sure we dare cut through the outer wall like that. Bravo!
On one particular cold but damp morning , all the internal framework and structure of our 400 revealed itself . At least I knew I was not going to be drilling through an inner support structure member ! Just had to make sure I did not drill through the edge of the internal box that holds the Nautilus component's .
Re: Ceiling Panels - 2023 T@b 320
What exactly did the dealer do to examine this? When they replaced the caulking around the fan on the roof, did they remove all the caulk and lift out the fan to have a look? Did they take the fan shroud off the inside of the trailer and look at as much as they could see there?
You mentioned "seals". What exactly did they check and where?
This would "appear" to be a fan leak. There have been a couple of "roof leaks" but they all seem to involve the seams at the edge of the trailer.
Re: Towing a 400
We tow with a 3rd gen Tacoma. It’s fine. Not great. But we don’t RV enough to justify upgrading. I know a few people who tow with SUVs.
I think it mainly comes down to powertrain. V8 with a lot of gears would be ideal. My personal opinion is anything with an undersized engine with a turbo on it isn’t built for longevity. So it may tow just fine but there could be reliability issues down the road.
If you don’t RV a lot then a Pilot is probably fine.

Re: Is Plug-in Solar Feasible for a T@B?
For a camper I would think running a solar panel through a microinverter and then dropping it back to DC voltage to charge the battery would be very inefficient.
