Good Luck you guy's.
Hey Tommy,
I was gonna ask if you have actually used a dump station yet? Because I have, and that 90 is nice because the "hole" has a brass lid on it with a pedal you step on to open, and if you did it right you don't get st***f all over just putting the hose in there. There is a concrete burm around the area for containment and water to rinse everything. But of coarse before you do anything, put on your nitrile gloves, and DO NOT scratch yer nose, until you have cleaned everything and washed up, even if it really, really itches. And it will. The reason I ask is that you may have way more hose than ya need.
I know I do.... Being Irish and all....
But seriously, you may be able to get rid of some of that and make your storage issue a lot smaller as well. Like a Home Depot bucket w/lid in the bed of the truck. I needed about a third of what I had, and luckily the hose has a connector in the middle, so I haven't contaminated half of it. The rest I have in one of those earth friendly shopping bags that you take with you to the store. All fits fine, flush master 2000 first, hose with the lids/plugs installed so no leaks next, and the 90 on top. I keep the gloves and the blue pellets separate so no contaminates. All is stored in the vented storage area where propane and pump and reefer condenser are located outside of cabin. That storage/access vented door is located above and left of the poop shoot and I keep the rinse hose in there as well, although I haven't needed it yet, the station has one hanging from a boom so it isn't laying in the wet region there, and you can rinse everything off, inside and out, before storing it.. My fresh H20 input door, and shore power inlet, and cable/antenna inlet are to left/front of that door. But I'm tellin ya, the 90 worked well and sealed, and the brass lid over the hole held it in there, like it was designed to do that....know what I mean?
When I pulled up the poop valve was maybe 5-6' from the hole.
So, why don't you use it first and see how it goes, what to leave in, what to leave out. Problem may solve itself....
just sayin'...

Ps. If you go with the pipe, see if there is a expandable plug available. They have a rubber bellows that expands when you tighten the wing nut. So glue on cap on one end, expandable plug in the other. May be cheaper and easier to remove/install than threaded fittings? And maybe some weep holes at bottom of tube.
