I had a few PM's recently regarding the DI rinse tank system I have installed. There are multiple ways to do this, but the design I prefer is utilizing 6x18 tanks. These will fit nicely in the bays of the RV as I have pictured, and have plenty of room to install different heads.
My original system utilized the pegboard bay and the
On-the-Go DI dual tank system.
The O2G is a complete kit ready to use and cost $405.00 shipped with the resin. It is available from amazon here:

What I did not like about this system is there was no way to easily bypass the filter, and the link between the tanks was prone to leaking.
I went about designing my own system from scratch, and found Pure Water Products.

Here is a cut/paste of my order:
2 ta501 Polyglass Mineral Tank; 6" x 18"(Almond)
2 bw524 Fleck Fine Mesh Bottom Basket Riser, 1.05" X 54"
2 wh900 Clack; In/Out Head, Vent Tap
2 bw650 Clack Bypass Valve, 1" male NPT
2 bw651 Clack Elbow Adapter, 1"
2 bw520 Fleck Top Basket, 1.05"
Total per set -- $189 ($378 for pair)
The clack heads with the bypass are very expensive @ $88 per tank, but they allow me to bypass the resin and deliver water at a higher pressure without wasting DI for the rinse process.
After buying the tanks, I then had to buy the resin.
By far, the best option so far is On-The-Go from Amazon:

$120.00 for both tanks, bringing total cost of my build to $498, or $95 more than buying the kit, and giving me a far better head that does not leak.
The Input/Output of the tank is a 1" NPT thread, so you will need reducers if you are going to use garden hose as I have done.
Amazon has these in 2-packs for $9.99 -

You will need a total of 4 adapters.
For the mounting bracket, I created these using a 3D printer, and then used 36" straps to secure the tanks.

As I mentioned in the video, I made a mistake with my first batch, and didn't install the upflow baskets. This resulted in all of the resin from tank 1 moving to tank2, and then proceeding to flow thru the rest of my pipes into the pressure washer. This was a huge mess, and one that you don't want to make.
Since I had a lot of fresh resin that was mixed, I purchased a 3rd tank, and made it a mix resin system.
As a result, I have a system that will take my terrible 500+ppm water to less than 3ppm, and should do so for a very long time.
