Question Completely Enclosed Bottom 245RB

The bottom of my Passport 245RB is completely covered.
I have recently touched up all the visible underbody components of my trailer.
It is a 2009, and the frame was showing some rust.
I am concerned that there may be rust under the Bottom Cover, which extends from just aft the front A frame, to the rear bumper.
Is the cover to:
A. To add some insulation to the trailer floor.
B. To aid in aerodynamics.
C. To help support underbody fittings, such as plumbing or wiring.
I'd like to inspect the bottom of the trailer before I store it for winter, but
I am reluctant to remove the bottom cover, for fear that C. might be the case.
Can anyone who has removed this cover advise me
Thanks
Mr. T.

I don't believe "C" is true; that said, I do believe A&B are part of the equation. The enclosed bottom also serves to protect vulnerable components from damage during travel (electrical, hoses, etc.).

Several people both here and on other forums have removed this barrier for either service, repairs, or modification issues.

There have been a number of threads on this topic already.

The material is called coroplast. It's basically corrugated plastic. They enclose the underbellies to add insulation capacity for three season camping.

Feel free to pull the screws and drop the panel as you see fit. You won't hurt anything.

The coroplast underbelly isn't supporting anything but it does provide a minimal amount of insulation and protection for wiring, holding tanks, and plumbing lines. Don't be fooled into thinking that it provides much in the way of insulation during cold temperatures. There are just too many holes and openings and too much empty air space inside the coroplast for it to do much in the way of stopping your pipes from freezing.

Just a reminder on coroplast removal. Usually it's one peace of material. I had to cut mine in 3 sections to remove. And to reinstall, I had to buy angle iron for the 3 cut sections for support. And do not forget the cans of spray foam.

My trailer even has a furnace duct that runs into the underbelly. I think that’s a futile effort, so I blocked that duct at the furnace.

Keystone also touts the underbelly covering as aerodynamic, so I vote for A&B.
