What is the material of main door inside

[trucking]

Hello I have a 2016 Kodiak Ultra Lite 22ft with main door inside panel cracks.
The cracks are not bad only four areas and they are not getting bigger yet.
What is the inside door panel material so I can seal the cracks.
Maybe an epoxy if plastic
Or fiber glass resin
Or what?
Thanks
Happy trails to you till we meet again

Well I think it is a plastic and it looks like a job for :
J-B Weld 50139 Plastic Bonder Body Panel Adhesive and Gap Filler Syringe

Nobody has a clue what the inside main door skin material is??

The main question is still unanswered.
What is the inside door panel (skin) material so I can seal the cracks.?
I have a new direction to the repair.
There is a product called PERMABOND TA4631 POLYOLEFIN BONDER I would like to try, but I need to know the interior skin material.
There are four different Permabond to pick from depending on material.
Thanks , Happy trails to you

When they tell me I will tell all of you,
Then all of you Dutchman owners will know.
Happy trails to you

Looks like you may have other issues with the door…. I think I see another spot that may crack just above the present cracks. I would pull the window to see if there is anything going on inside the door.

I did a search for the issue you have with the door and found an interesting thread on IRV2. https://www.irv2.com/forums/f50/entr...in-612447.html

Yes it does does.
New rain/snow storm on its way in,
When the Storm passes I'm going g to do that.
It's not bad for 8 years old, I have seen worse in a shorter time.
These inside door skin cracks are on lots of RV.
Thanks.

Thank you , I agree replacing the inter skin is not worth the effort and cost of replacing the door is to much.
For my door I'm pretty sure removal of window frame for inspection and using the correct epoxy on the four cracks then adhere a 3/4 " or 1/2" strip to cover the patch.
Same strip that is on the ceiling.
As soon as I find out what material is the skin ill know what epoxy to use.
Happy trails

I am having the same issue on my 2018 Voltage--built in late 2017. I suspect it is related to heat. I store my trailer outdoors and that side faces south in So. Cal so it gets hot. I am thinking the only repair might be to try to put some type of wall paper on it. I am not about to replace the door or try to reskin it. I don't love the way it looks but it's mostly hidden by the screen door when closed and I have just accepted it as normal wear and tear for my cheaply built Dutchmen/Lipper RV.

I have plenty of other issues to worry about related to age that consume my time.

I have received a email from Libbert about what the inside skin material is and all they said wad it is a plastic pebble.
So I replied to them what kind of plastic.
There are 7 types of plastic.
So I'm waiting for the second reply.
I would call them but I want their reply to be in black and white not just over the phone.
Happy trails

Third update:
I Sent a photo of the door tag with all the information then they replied.
I received an email from Libbert.
Hello Paul,

This door includes a fiberglass skin. If you have any additional questions, please don't hesitate to reach out.

4th update:
Now that I know the doof skin is a fiberglass sheet.
I have lots of fiberglass bonding products to pick from.
So I'm going to use what I use on my boat and have in my garage.

The door on my 2018 Kodiak did the same thing. The manufacturer sent me a whole new door and frame under warranty. I suspect it was the Arizona heat.
If they had not sent me one for free, I was going to replace the inner skin material myself with a very similar material that I had found at Lowe’s . During the installation I was going to leave enough play in the edges to allow for flexibility. I think the old one cracked because there wasn’t enough flexibility for expansion in the heat.
