Gray Water drain access

[IsataMatata]

In my Isata 5, It appears that the drain pipe from my gray tank to the tee fitting where the bath sink join was not glued properly, if at all. The fitting is too tight to pull apart to get glue around the fittings to seal them properly. My question is..What is the best way to get the fitting apart?
My thoughts are to drop the gray tank, is this an easy job? Is this something a Mobile service person can take care of easily?
Thanks

The pictures show where the drain is located. I removed a panel beside the bed to locate the leak.

That might be one for a dealer...

This was engineerings response.

"The sanitary tee on its back shouldn’t have any water running through it vertically. However as you can see that line horizontally has the kitchen and shower running through it. Best way to fix this if it is indeed the tee is to cut the ABS pipe about 2” pass the tee facing the bed side. Remove or spin the bed section a bit out of the way. On the bed section pipe slip a no hub coupler 1-1/2" all the way over the pipe. Dry the inside of the tee and pipe until no moisture is left in it (hair dryer works well here after you mop up the puddled water). Take ABS glue with a long Glue Dobber and completely coat both sides of the interior of the tee. Let it set to dry for 3-6 hours. Move the bed section of the pipe back into place and slide half of the no hub coupler onto the other section of pipe and tighten the band.
Fill up the kitchen sink, then turn the shower on. While the shower is running pull the basket strainer(s) up and let the kitchen sink drain out. Go inspect the tee for leaks you may do this until your satisfied the problem is solved. Reinstall the plumbing cover."

Thanks for the .pdf, that is great information to have on hand.

Update...at first, the dealer thought the bath vanity needed to be removed to access plumbing. Luckily, one of their techs was able to completely removed the original tee and replaced it with a rubber tee without removing the tank or cabinetry.

Sure wish I could find a pdf like that for mine.
