What is your plan for venting and draining the GW tank?

What would happen if tank was placed directly below pan and maybe slightly offset for p trap placement or maybe hep-vo? But out of curiosity, what if it was just directly below without any trap of any sort?

You would absolutely want a trap or Hepvo it would reek otherwise. I really like the below series of articles although it isn't directly related to your quandary. I used a Hepvo under the shower pan which was elevated on a frame about 3" tall, this allowed me to route the post Hepvo plumbing over the frame and down into the tank.

Water, Water, Everywhere!

I don't think the frame member is solid. Have you looked at it? Maybe it is in that era. I don't think you want that trap extending below your trailer. You'll have issues with freezing possibly, or getting knocked around maybe.

Even if your frame is solid, I would recommend a couple things:

1. cut a hole and weld a ring of steel to support the floor and the rail on both sides.
2. Cut a cole and bolt plates on both sides. Get flat steel about 2 feet long that will fit on either side of the cross member. Drill hole through that, place bolts 3 on each side of the hole to bind it, zig zag pattern.

Run the drain line through that. Get a P trap in there to assist with gasses and with the sucking action to drain your shower.

Don't do this with the frame rails, just the cross members.

the crossmembers aren't solid. they are 'c' channel. truckasarus, you don't have a problem draining your shower pan using the hepvo? The the other issue is that this is a 53. our friend, The OP, is very tall and as it is he can barely stand up in the trailer. he's already got to 'hunch'. raising the shower pan is not out of the question, but it is still located overtop of the bay next to the grey tank; the shower pan is over the axle and grey tanks are fore and aft of the axle.

Excuse the rough sketch:

something like this would raise the shower pan enough to run the lines OVER the frame but would make it impossible for ansrew, a future full timer, to stand and shower.

Even with a "P" trap. It would not extend below the frame rail and would be above the belly pan.
Not sure how the "H" valve works, but there are no moving parts in a "P" trap.

what i did . . .

Personally I chose to lose the 3 inches . . . I'm 6'-3" and didn't really have it to lose but other "wishes" took precedence. When finished I'll end up with a "wet bath" and will be forced to take my showers sitting down. Actually I would have had a hard time standing up because of the Ceiling Curve so the 3" in my case doesn't make that much difference.

. . . and again, a friend here on the forums uses one of those Shower Sump Pumps and is pretty satisfied. It's mounted directly to the bottom of the Plywood and the bottom of his tub is right against the top of the plywood. I think it has a 3/4" flexible hose going to his gray tank. The important thing would be to make it accessible/serviceable.

NJtoNC I think MarkR and you have the right idea, those extra inches won't be missed as andrew was going to have to sit down anyways

My question is, would we then move the black tank back to make room for the shower drain pipe?

we'll be having a vent at the opposite end venting through the roof and draining would be normal direct connect to the dump valves

unfortunately we would have to get a custom tank for it to fit directly underneath the shower pan, which isn't in our current budget

No problem with the drainage from the Hepflo's, I have only had them installed on the Overlander for 2 years now so no long term validation from me but I do like them and will use them on the Sovereign for sure. The attached pic hopefully shows my set up, you can just see the short base with a section of Teklam beneath the tub. Luckily I'm not tall...
