Based on Amazon reviews and Q/A I don't think there are problems.

I first saw these on Walmart and thought it was to good to be true.

I may add a tank and I'll source from them.

It's strange the "vanlife add tax (VAT)" is missing.

 

I've seen them on Amazon also...they seem to have the best reviews among the others. I wish the spin welding stuff wasn't so expensive. Really cool process though.

 

Anyone get a tank from these guys yet?
Curious how soft the plastic is on these tanks. They make sure to note not to hang them with straps.

 

They have a 10 gal tank that has the perfect dimensions to fit under the van, between the floor supports in the section forward of the E brake bracket. But I would have to hang it with straps. Hoping it's not too soft.
It's only $25.

Welcome to Class A Customs -

 

Their website said you could add or relocate fittings for $10 ea. It kept saying to "fill out form", but I got all the way to the checkout page and there was never a field to fill out and let them know where you wanted the fittings.
I sent an email and if I don't hear back by tomorrow, I'll call and see if I can get any info on how they operate.

 

I have bought 3 tanks from them. I have purchased a 33 gallon tank that I'm using for greywater. I purchased a 46 gallon tank for freshwater and had fittings moved and deleted with their form. I also purchased an 18 and 1/2 gallon black tank from them. You can get fittings anywhere you like and I emailed the diagram to them after I placed my order. But emails before purchase were responded in a timely manner as well. The sides of the tank will bow out slightly when full but it has not been an issue. I added fittings into the threaded ports that came on the tank to adapt to PVC, flexible hose, and pex. They need to be placed on a flat surface and supported fullt from underneath. They are not designed to hang. If anyone has specific questions I'll be happy to attempt to answer them. Hope that helps the group.

 

It does help, thanks.
I'm looking at the 10 gal for gray water.
It's 24" L x 13" W and only 8" H.
So I probably won't get much bulge in the sides.
I was more curious about fitting placement. Granted, I was looking on my phone. Sometimes "mobile" versions of websites are different.
I'll try on the laptop and maybe the form will show up.

 

There is a layout form on the website, a PDF, somewhere without going through the cart. The spin fittings are fine, but they are about 1/2 inch from the corner, so my side drain on my tank doesn't completely empty it. I could have put it on the bottom, but that was not best for my layout.

 

Here is a close-up of my fresh tank fitting that goes to my pump and also to a drain to empty it. The spin fitting is a 1/2 inch npt and then I inserted a 1/2 inch npt to 1/2 inch PEX adapter to crimp on my blue PEX. You can see that I would not be able to get the last quarter to half inch of water out of that tank.

 

That's probably a good thing though.
The pump won't grab any sediment that might make it to the bottom.

 

And the van generally is higher in the back. My fresh pickup and gray drains are forward, so the higher back end helps me out.

 

So, by "spin fittings", I'm guessing they spin them and the friction melts them in?

 

You're correct, I've used roto mold tanks on boats, there are other ways to install fitting. The spin on fittings are better. There is only one glue that works on roto mold tanks and that's West GFlex 455, you do need to flash the tank to adhere. Flashing is you sand first and run a propane torch over slowly about an inch an second.

 

I believe that is correct.

 

I had a “spinweld“ grey water tank made - expensive, but made to exactly what I needed to fit under.

 

When I added in-flows and a vent to my grey tank, I used these rubber grommet slip fittings. No special tools other than a hole saw. Very tight and no leaks. The out-flow has a threaded fitting that was spin-welded.

Anyone has photos of their tanks fitted under the vehicle in front of the parking brake?

 

I've used a similar water holding tank FTC Tanks, and the price is great. The grey tank should fit well under the van. You can add fittings yourself, but make sure to use the right tools and sealants to avoid leaks.

 

Can u park on incline to empty better?
