Crazy thought:
Why not set up the tank to stay in the car? Put 100’ of 3/8” or 1/2” hose on a reel or in a bucket for your supply line; and 200’ or a little more of 1/4” polyurethane air hose for your pole.
Put a plastic mat/boot tray under the tank, secure it well, and keep on the lookout for leaks 
I guess you did not read my comment, but that looks to me like a rented tank. You SHOULD NOT lay it over or it will be worthless! Call the place you rented it from, they are the experts, since no one here rents these things.
That… Is a really good idea… the only issue right now is the temperature here. 
but soon that should be fine, and if I build it right I can make it removable when needed. What have you guys found is the average needed length to be able to make it halfway around most homes? is 200ft enough?
I did read your comment, this is not a rented tank, it’s from WCR, although It most likely works the same. I’ll make sure and research properly what I can and can’t do. 
What I DID learn today first time using WFP was that having a 100’ garden hose and 50’ or whatever comes with the WCR xero pro pole is a recipe for unnecessary hard work and trouble constantly moving the tank around the house. Also learned that you can’t connect the garden hose directly to the DI tank, you need an adapter. Also learned that dog poop and WFP is bad combination when the persons dog has left pooh on the padio. Also learned that WFP work is so awesome and so so worth it. Pretty good day in the end. I had to work for a total of 8 hours on two different houses and made a total of 480 before tax, so I’m happy with today’s work and very happy with the performance of my WFP!
I carry 2, 3 feet lengths of garden hose, 1 from the spigot to the DI then from DI to hose reel then have 175’ of pole hose which is I think 8mm. I sit the DI tank right next to the tap and drag the 8mm hose around.
Almost all houses are able to be done without moving the DI tank at all and with minimal set up and pack up time due to the short hoses.
So 175 feet of hose is enough to get all the way around the house (or halfway rather)? Have you ever ran into the problem of not having enough?
Hey there 
You didnt get a quick connect with your package? Let me know if I can help. Just tag me.
Traveling with your DI tank on its side is no problem. You can get channeling though if you try and operate it laying down. For best results use standing up.
Only on commercial jobs where I already knew I would only be able to do each section before moving the tank.
On resi I have done some quite large jobs with just a centralized tank placement, its all about choosing the right tap.
This is what I was wondering too. Luke the Window Cleaner always lays his xero pure down when he cleans… anyone have any ideas if this is ok, or at a slight angle? I’m asking because I have converted my SUV into a van type vehicle, where I can just run the WFP straight out of the vehicle, but I can either have it at about a 45 degree angle, or laid down. What are your guys thoughts?
Hi Aaron - the Xero Pure is designed to operate laying down or standing up. Either is fine.
@Chris there is a chance that I missed something, I’ll double check when I get a chance, but as far as I know I got a quick connect to go from the “out” to the wfp, but not one to go from the spigot to the di tank. I purchased a cheap adapter though, so it works okay.
