Prowler Lynx 27LX - Combine gray water tanks?

Hey guys,

My Prowler has 3 tanks. One 35gal gray for the rear shower, One 35gal kitchen gray tank and one 35gal black tank for you guessed it, the poop shoot.

Maybe i take too long of a shower, but it seems that the shower tank fills up pretty quickly after just a few showers. I have to say that 35 gallons is a pretty decent size for a bumper pull camper, but for me it doesn't seem to be enough. Sometimes I have to skimp on campsite amenities due to my last minute nature and so, many times I end up on pads with no sewer.

The kitchen tank never ever gets enough use to fill up quickly, so I'd been thinking about ways to connect or equalize the levels in both tanks and effectively double my holding capacity.

As as with many camper configurations I've seen, my gray tanks are not next to each other. Between them lurk the black tank, filled with offensive liquids and toxic gases. Not something I want to mess with while trying to hookup a line between the grays. As you can see by the pics, the tank far to the right is the shower gray and has its own dump line. The kitchen and black tank share the same dump line.

Kitchen gray on left. Black tank on right. Shower tank to the extreme right, barely visible in this pic.

So, should I buy some 1" black ABS pipe and connections and create a "C" shaped pipe to curve around the black tank and connect to the sides on both grays several inches above the dump line, so the shower tank has to fill up to 3/4 before it begins cascading to the kitchen tank? Or is there a better way? Will I have problems with air pressure or "burps" from one or both of the tanks?

does anyone have pictures showing how they equalized their gray tanks??

thanks guys!

Moved on to the next thing...
We have the same tank arrangement on our Trail Runner . . . only ours has the rear kitchen instead of the rear bath.

Problem with ours is that one drain is at the very back of the trailer and the other is up in front of the tires.

It is kind of a PITA hooking up to the sewer at the campgrounds.

I noticed on the 2014 version of our trailer that they flopped the bathroom around from what ours is like . . . I wonder if maybe tank issues was Heartland's reasoning for this.
