2018 376th Momentum belly sagging!!

[Batman]

Noticed this today, the bottom plastic covering is in tact, But it is sagging really bad.. Has anyone ran into this and should I be concerned?

Push up on it and check to feel if there's weight above it or sloshing (make sure it's not fluid building up would be my primary concern). Could always drop it to make sure and then re-attach. Could be just some fasteners failed... could be worse. Better to find out sooner than later.

Newly full timing in our 2021 Momentum 395MS-R with our tow pig being a 2021 F-450 KR

I will be pulling it down tomorrow, I don't feel anything sloshing.. We just came from a very long trip and it was raining and very very windy.. maybe the rain worked its way up there and caused it to sag... that is what I am hoping anyhow.

No sloshing is good. Good luck and keep us posted.

Here is a thread I started years ago on this very subject. (and several ideas for "fix" including mine)

I can tell you too much about this material... lol. Fortunately, I don't supply this industry. However, it is practically all the same, and is not really meant to hang across long, unsupported spans. It will sag more and more with time and high temperature. Provided you have no leak or broken member that exacerbated this, just add support. A piece of steel angle or channel spanning and attached to the frame beam bottom flanged will take of this.

Be ready when you go in. It's a mess. Wires, cables and water lines draped over trusses. An accident waiting to happen. Take your time and address all the issues you may find. Good luck it's a Pain in the.....

I had the same thing happen after driving all day in the rain...water. Punched a small hole in the coroplast at the low point and allowed it to drain.

Oh yes. Check for water leaks. That could be causing the sag but not necessarly. I've supported mine in the center with stripps of aluminum angle. If you do go into the belly of the beast be ready to clean up a mess. There are wires and hoses drapped over the frame trusses everywhere, an accident waiting to happen. Good time to clean up that mess, if you go in. I even found my Black Tank falling out. Long sad story, since day one. I have mine tore appart right now. Good luck. 2018 376
