Opened area under kitchen sink & glad i did

I would appreciate so assistance in locating a part to protect tubing and electrical wiring that is installed thru the TT floor. I appears that on the lower price point TT Forest River just opens a hole in the floor and stuffs the tubes thru & then throws some foam at the hole. See pix 2 & 3 to see what part Im looking for.

I opened up the area underneath the kitchen sink in our 2018 Wildwood for the following reasons;

A/ Fresh water tank would not fill from outside filler entry, as I listed on my May 2 post.

B/ The counter extender shelf was not stable and had to correct the factory's poor installation, so it could support some weight when used.

C/ Cabinet storage under the sink consisted of ONE shelf that was partly blocked by the sink P-trap.

D/ Using the space next to the water pump on the end of the cabinet for a cubby for shoes (away from the front of the door) by relocating a heater vent outlet.

I have attached photos to show what I found when I opened up

1/ The Fresh water tank vent (black tube in PIX) was crushed not in the tank. It was frozen in place by a dab of foam, Need the thru the floor gasket to fix the opening so bugs & stuff will not come in.

2/ The backboard intended to support the counter extension was only stapled on one end, and therefore the screws to the extension were only into the 1/8" panel board.

3/ The area under the sink had ALL the trailer construction debris; sawdust, broke would slats, etc. See the pix. This debris would make its way into the drawers, and other things.

4/ The P trap for the double sink was placed blocking the only shelf partial useable under the sink. I found a device called a "WATERLESS HEPVO 1-1/2" TRAP" that will replace the huge P trap & the required vent.

5/ Finally, the water pump was just sitting on a piece of rubber material, not fastened down except thru the ridge pipes connecting it to the water system. No wonder it made so much noise.

I say all this to suggest that you pull drawers out and open cabinet doors wide in your TT, to correct the many things the factory's QA did not see or look for.

Help with the part at the first paragraph of the note would be appreciated, so I can properly close up the kitchen

Thanks in advance for any ones assistance.

It's not only on the lower price point TT, they use that expandable foam on everything. It's what has prevented me from relocating my Schwintek controller. I look at it as kind of an RV duct tape... got a large hole? Fill it with foam!!!!

These things are built wonderfully aren't they? I made a post about my FDEN 40 on this but nobody found it worthy of a response I guess.
Anyhow I think the part your looking for is called a estcushen? Spelling is way off but pronounced something like Scushin. They are used in plumbing where a pipe protrudes through a hole in the wall or floor. It kind of gives it a finish trim and supports the pipe at the same time. Hope this helps.

I was surprised to see a similar hole where my fresh line feed come in under the sink in my Wildwood FSX. In my case, no spray foam or anything, just a hole and some daylight. Not to hijack the thread but what *should* I use to fill it? Iím worried about cold and vermin. The spray foam seemed like a decent idea but from what Iím hearing, it would make things tough when it comes time to replace something.

Sealing floor opening

I sealed the open holes to the TT's water tank with "Self Adhesive Weather Stripping Foam Strip[/URL]" cut into 6 x 6" square Here's a link to the AMAZON PAGE [URL=[/URL].
This allowed the opening to be 95% closed then I applied foam onto the weather stripping to seal the other 5%.
Now if I need to get back into the area, I just pull off the self adhesive stripping and off comes the foam as well.

Attached is the install before the foam
