Kitchen sink drain routing

I have been noticing my kitchen sink draining slowly lately.  So I took the p-trap off thinking that was prob but it was clean.  As I started to inspect further, I notice down at the bottom of the flooring under sink it was a bit wet.  That's never a good sign.

Removal of the interior covering was not difficult.  What I found was a bit perplexing though.    The fixed PVC plumbing/drain feeds into a what appears to be a "flex" tubing (about 1 3/4 or 2 inch) that then feeds back into the wall around the front water closet.  For reference the kitchen and sink area is part of the slide.  The water closet is not.  So the "flexible" looking part makes sense in accounting for slide movement/etc. 

As I dug further though I noticed the "flexible" is really NOT that flexible.  It is cable-tied to moving plumbing tree so as to move with slide.  But as it moves in, it was apparently getting very pinched.  Not being really that flexible, over time (this is a 2014 coach) its obviously developed wear/tear from being strapped down to the plumbing tree and not really being flexible.  This is where the leak has developed. 

The sever pinching looks like it accounts for slower/slowing drain as the tube becomes very constricted at that bend and from the cable tie down. 

I am thinking i can cut this tubing just after the leak and just before and possible put some other PVC/flex in place of the bend. 

Has anyone encountered this or done a similar MacGyver fix?  Added pictures for reference here

Thanks

Tom, I would think the P trap could be rotated towards the exit and delete all that extra mess. No clue why all that was added. I would attempt to delete all the flex.

That's an interesting suggestion.  I would have to modify the cover that goes over but perhaps an easier solution then replacing/splicing something in between the bend there now. 

I need to head to Lowes and see what options on part/connectors they have.  Looks like the flex line was just glued right into a PVC elbow originally.  Not really a compression fitting but then it is just a drain so prob not necessary.

I go with Scott I looks like you have about two feet of piping that is unnecessary. If you
don't want to go with Scotts plan you could glue a PVC elbow in where the kink is.

That messy flex is giving MacYver a bad name.

That flexible section looks like pool & spa pvc pipe which is somewhat flexible and does glue into schedule 40 pvc fittings.  If your sink is in the slide, it looks like you would need at least that much to accommodate the extra 24" when the slide is extended.  Make sure you don't make it too short.

actually in the picture the slide is extended.  I am still trying to wrap my head around why its bent so sever at that point.  I havent had a chance to put the slide in yet but it would seem the flex hose should relax/slack with slide in. 

I am almost thinking now that the over all flex part was too short to begin with or someone has already shorten it at some point.  Spidey sense tell me it should follow the natural curve of the rest of that chain/stack and not sharp bend. 

What you cant see in the pictures is the flexible part has been severely pinched from both sides restricting the flow to probably 1/8 of the diameter.    When I tried to see about storing the "natural" shape at the bend its not changing at all perhaps because of severity of the change in direction. 

At this point I am shopping parts on line.  The flex looks to bee 1 3/4 diameter which doesnt seem to be easily available locally.
