So, I bought a toy hauler for a decent deal. The previous owners lived in it for a while while having a house build. They did some weird stuff to it. Long story short, there is a 2" hole in the bottom of the water tank. I am not sure if it was for a drain or not, as it isn't threaded. I need a bulkhead fitting to seal the hole and I can add a plug or valve for drainage.

I can't use a typical bulkhead fitting, as I can't get the fitting or the nut inside the tank for assembly.

Is there a fitting that would work for me?

Looks like a friction weld fitting failed and broke off. If you have a plastic fab company near you you could pull it clean it up and take it there to weld a patch over it. If you need a bung there have them weld in a coupling. It's polyethylene BTW
 
Set the camper on fire, they are all pieces of shit. My door is getting to the point where it won't close without slamming the shit out of it 3 times. I topped off the water tank a few days ago and found water running out of the pantry across the floor. There is an improving chance that Jewish lightning will hit this fucker soon.
 
that looks nasty....undo that cradle and slip a new tank in there.

these.

but if you really want to fix it, then plastic welding is really the only option that doesn't suck balls.

And get those wires out from in between the tank and its support while its out so they don't short.
 
Search "Expansion Plug" on McMaster. Like the PVC test plug above, but available in stainless or this style, which might actually work:

That was probably a largeish drain valve so you could quickly dump the tank. My buddies toyhauler had that and it confused the hell out of us for a while but it's pretty nice to be able to dump the excess for hauling instead of pissing a 1/4" stream for the entire trip home.

This post is not without merit. :laughing:

They are all built like shit. This one has direct access for rodents to get to the inside. And there isn't much space for insulation between the living space and the storage area.
 
I decided to look at my 1 year old campers door last night to see if there is anything to de done. After serious investigation, the top half of the top hinge froze and was actually twisting the hinge causing the door to be out of alignment. I hosed the hinges down with PB Blast and voila, the door closes right without having to slam the shit out of it. It still isn't completely unfroze as it makes some terrible noise when it is opening/closing but 100% improved. I love the idea of campers but really hate owning one.

That wasn't a friction hinge right?

ran into something similar with my last camper, filing the mating surfaces so they were rounded was all I needed to do. those things tend to hang up all the time on each other from minor frame tweaking when leveled, that fixed it for the time I had it
 
You could get a brass bulkhead and cut a slot in one side of the nut about the thickness of the tank wall. Then you can get the nut in the tank and if you're careful you can thread the bulkhead into it and tighten it down. You are only going to seal 1psi or less, it would hold that forever. Make sense?
 
Use this type of fitting from RV store. has oval nut that you leave on end of threads then slips through the hole. Align straight then tighten with o-ring on outside of tank.
