The subfloor is cut! Everything pretty much lines up. I didn't expect it to be perfect because I read about the frame skewing without the shell and subfloor on it, thankfully I didn't have to drive it around too much to get it on the other side of my driveway, and I haven't turned it on its side to access the belly pan.

That old piece is in there as kind of a corner stone to line up everything else off of since it's holes were the least destroyed from removing the bolts and I can see through them to the holes in the frame.

Next I'm going to:
1.prep this wood with resin
2.plot out my holding tanks
3.research good insulation for under the floor
4.clean and prep the frame/paint it
5.figure out what to do about the belly pan.
6.seek therapy to pinpoint why I take on hobbies like this to punish myself.

Not a great pic of my skid plate, and my frame has been sandblasted and epoxy coated. The rectangular hole cut in my main frame rail (which weakened the rail) for the black tank drain was eliminated when I had my welder box in the main frame rails from the wheels to the bumper. There is also a hole in the skid plate, which could accommodate a drain line. It originally was for the city water connection, but I relocated that. Sorry for the grainy pic....can't located the original.

Sand blasting a frame is overkill me thinks, also you lose too much material in the process. Powdercoating is also prone to chipping, and having it rust from inside out. Sand, prep, base and paint is the way to go. Just my opinion.

Marco looking good bro. Your project is got me wanting to pick up a beater and do a complete overhaul but I am not sure if my wife would hang around for it! She has told me another project and she's out! Lmao

Don't do it shaggy! For the love of god don't do it!

Arktos, thank you so so much for the pic, it cleared everything up for me. The PO welded a bunch of stuff on, which left me guessing what was stock and what was him. That piece seemed very janky to me, especially the hole cut for the incoming water, must have been that factory worker's first day on the job. And the waste hole definitely compromises the integrity of that corner of the frame. I'll figure out how to spice that area up a bit.

Cwf, this will surely be my first and last time doing this. The Airstream Marco Edition is going to be a one-off, I guess that will make it worth buku bucks (spelling?). Jk btw.

Okay team! So I started designing my new holding tank system and had a question...
Is there any foreseeable problems with having the shower drain directly into the gray holding tank? I'd hate to have to elevate my shower floor to make room for a P trap and the law of gravity. I'm 6'2 and headroom in the curved roof corner is scarce.

I believe the problem is....without a p-trap, fumes and 'water' can slosh out of your drain/tank while you are towing. I've seen some talk of a valve that can be adapted for this situation..... but you need something to keep all that stuff where it belongs....in the tank.... not on your floors.

Yes the shower will act as your black tank vent which would be very much smelly! You need the trap and maybe a gray tank would be much better!
Cliff


Yes I said that! Or did I?

Marco... i would personally prefer gray water "sloshing" up.. than the dumper... Also, Imagine...
you are headed downhill and have to slam on the brakes.. the full load in the tank moves forward....you will need a big shower basin to handle the flow...then have a nice aroma when you stop for the night.

So, I am also 6'2"... and to 'lean over' a bit, or sit on the shower ledge works great.... of course our Excella has a different shaped shell..

Why not build the correct height base and add a seat in the 'shower'? or, do like the SOB's... cut a hole in the roof and install a dome... you can shower and look around outside at the same time!

Hey Cliff, sorry for my cruddy diagram, but that pie shaped thing is the black tank, it would have its own vent. The box on the bottom is the gray tank.

I looked for a 1-way drain valve thing that would prevent the water and fumes from coming back up- such a thing doesn't exist, so all you inventors out there, I can't speak for everyone, but I'll gladly pay $30 for such a thing.

My best plan so far would be to have a drain I can plug when I'm not using it. I'm still all ears though. I imagine I'd use the plug no matter what anyway.

Cwf,
The dome thing... no. The seat, maybe

Here's something that would need less clearance. Hepvo Waterless Valve

Hepvo Waterless Valve

Do a search on the forums, I think a few members have used them

Great job you've been doing!

We used the Hepvo Waterless Valve in our shower as well as the galley sink. So far so good! I think Airstream uses them in the Interstate RV's....not positive tho.

Reinergirl and Becky,
This thing looks like some kind of evil witch sorcery.... And I'm all about it!!! Thank you so much, this is PERFECT! I'm going to get 3 of these puppies.

P traps seem like a bad idea in a trailer that will be bouncing around, or sitting for a long time, the water will either shake out of the trap or evaporate. But the gremlins that live in this valve will do an amazing job! Thanks again!
