Many of us 2024 Micro Minnie owners have wondered if Winnebago addressed the lack of good water tank support that was seen in previous years. As the subject says, Winnebago did in fact address the water tank support issue. I accessed the void above the belly membrane fully expecting I was going to add water tank supports. However, what I found was a 5/8" or 3/4" sheet of chipboard under the water tank. As seen in the pictures, it spans the full width of the tank and sits between the two angle iron cross supports.
I don't see any screws securing the sheet in place, but I don't know if they may have used any adhesive between the wood and angle iron. The one thing I saw that concerns me a little is the passenger side edge of the sheet is very close to the protruding part of the tank that has the drain connected to it. If it touches and rubs, it could rub a hole in that part of the tank.
These two pictures are after I dropped the front edge of the belly membrane, and I was looking back at the edge of the water tank. The bottom of the picture is the top of the belly membrane with the foil layer across it. (There's an extra waste strip of belly membrane sitting with the wires. I guess the mfr left it there instead of disposing of it.)
The next pictures are different angles showing the sheet of chipboard under the tank. I didn't drop the whole membrane from the front (where I took the first pictures) all the way back to the axles. Instead, I sliced across the membrane just in front of where the water tank is and where the second aluminum support is screwed into a cross member to support the membrane. This is just a few inches in front of the front angle iron that supports the water tank. I was initially thinking I was going to face dropping the membrane to add water tank supports, and I didn't see the point in removing the front section of membrane. So, these pictures are looking through that split part of the membrane.
This next one is a tight look at the driver's side of the wood sheet with some wires next to it running fore and aft. This picture and the next also show the angle iron that the sheet of chipboard sits on.
And these last pics show how I put things back. I first injected some of the black sealant foam (sticky stuff!), put the two sections of membrane back up in place, ran a 4" wide piece of belly membrane tape over the split in the membrane across the entire 5" span, and then reinstalled the aluminum support strip that's held by 4 self taping screws.
After injecting the foam on the sides and between the front edge of the belly membrane and metal cross member, I reinstalled the aluminum strip that holds the front edge in place. I also added a layer of the 4" belly tape over that front edge as an added level of insurance. Then I crawled around under the trailer and injected more foam wherever I saw the mfr didn't do a good enough job.
