I wish you well with the sale, but being realistic, your complete set-up is probably worth around $4500 - max - and that would be in March. For me, I would never buy a 7 year old van from Wisconsin (used to live there) when I can buy the same van here in VA for $2K or less. Many of us in the real world find it too easy to see the flaws in your set-up. Not having hot water is a problem, so is 27 minutes of water. 8 gpm is great for flatwork, but not having hot water is a problem. Any chance you could return the pw and trade for something with heat?
Not trying to beat you up, just being realistic. As I recall, you have been trying to sell this set-up for quite some time. You may be better off parting it out.
