    @Robermcm For the rear passenger one in the latest pics, can you access it for bleeding by just reaching in or do you need to remove the panel as mentioned earlier in this thread?
    Yes, it’s easily reachable and has (in my case at least) some slack so you can gently pull it up to open.

    Mine is a (April) 2018 400 and I haven't found any manual bleeder valves.  Just the automatic one.

    I've pretty much gutted my interior and found 6 convectors so far.  In what I think is the direction of flow: Behind the bed in the tail of the trailer. Under the sink. Under the porthole by the door. Under the front of the dinette.  Under the driver's side porthole.  Under the shower.

    I'll probably add a couple when I'm fixing corrosion.  Yay.

    My 2019 400 was an October 2018 build and has one manual bleed under a cover under the shower on the solid pipe loop (not a convector like the others). It has a small plastic cover with two screws to remove.

    You are correct.  I located that one yesterday evening while I was "following the flow".  For others facing this, here's what it looks like removed.  Two screws at the top are shown in the pic from @qhumberd above.  That allows removal of the plastic cap you see in the top left of my photo.  Then some probably pretty weak plastic clips hold the Alde tubes in place.  Be gentle.  So now, I think I'm at 7 convectors.  Also, I should clean my shower.
