A couple of people have asked what I did to use the built-in 15 like a Portable. I don't feel like I have done anything that others haven't done but there was some interest in seeing pictures of what I've done.
I actually had to do two things:
First - I had to convert the 3/8 inch female connection on the fill valve to a 3/4 inch male machine thread use with a Unicoupler. I bought a 3/8 inch by 1/2 inch brass Nipple as they call them and a 1/2 inch to 3/4 adapter. I then screwed the Unicoupler on and had my water connection. I have a leak right now in the fill valve but I have a replacement sourced and on the way (thanks Steve!!).
This is what it looks like connected. I'll follow this with a picture of the cart I built.
