Hi Ken,
I won't know anything real until I get a set in my hot little hands and see what they do and don't offer. I have been looking for two primary things to fit the needs of what I hear most on this forum - 1) cheap and 2) low enough they do not require lifting the wheels off the ground or compensating rear blocks. I am trying to mitigate the suspension settling time issue if I can.
The idea for the kit I have in mind is one that nearly anyone can use. It would include a set of instructions including your caster = x times camber change where x = 1.91 for a 15 degree turn and x = 1.43 for a 20 degree turn each way. Hardware would include front and rear ride height blocks for simple go/no go measurements, roll-on turn plates with a simple to use 15 or 20 degree turn indicator, a digital level, a tire stand off that will clear the lug nuts and hub covers on Alcoa rims and which sports toe measuring arms that clear the front and rear of the front tires in the straight ahead position and a tape measure.
This should be sufficient for anyone at home or a rally where there is a handy flat concrete slab can at least check their ride height and alignment. If they want to actually change the alignment and feel comfortable with the safety requirements they would be able to do so. If this goes together, and if there is sufficient interest, then I will be recommending a rental fee and a time limit so every user has skin in the game (no "I want it free" in my vocabulary) and so every club member would have an equal shot if and when they want it. If it is used at rallies, I will be recommending a seminar showing how the kit is to be used followed by each interested person performing the check themselves with instructor supervision so they know what is going on and how to do it themselves.
For those who wish to raise the coach and place the turn plates under the wheels where lateral movement is required, I have a method in mind but will wait until I see these units before talking more about it. I do expect them to have good, accurate angle scales but only at the zero, 15 and 20 degree marks. Hope this helps.

Jerry,
Do the turn plates you're considering permit lateral movement as well as
rotation? Without that feature, I don't see how any turn plate can be of
any value since the wheels must be able to move laterally when lowered onto
the plates. If they have good, accurate, angle scales, even I'd be
interested.
Thanks,
Ken H.
