Thanks Rick for starting this.
Just to throw some more info out there from my searching.

The Dobinson 675v is a LT 4th gen rear coil. It provides the 4th gen's 2.5" of lift on average in stock form. That would provide us with 3.5" of lift due to the OE 4th gen spring providing about 1" of lift to start with. With extra weight it would bring that down some.
The Dobinson 210v is the stock height extra weight LC front spring, and from what @Black798 has told me it offers about 3.5" of lift with the extra weight.

I did have 861's, rear swingout and drawer system, but almost 5" of lift, it was just too much for me. I will probably order the 675v and see what those provide in the next couple months.

Free height is key for a spring not falling out, it would have to be at least 480mm to not leave a worry of them doing so.
