Need some help... Re. Warp Core Package on 2015 CS

We have an opportunity to purchase a lightly used 2015 CS with the 1600 ah lithium batteries + 600w solar. It is out of state and I only have pictures. The battery Panel (BMS) is not made up of eight battery control panels. It has just one with two toggle-type switches, one to activate the BMS, the other to turn on the display panel which shows the four banks minimum and maximum voltages and temperatures.

I think this is an older version of the current ecotrec modular system. Is anyone familiar with this and have and comments or concerns?

This is a rare bird, only reported on some early Ecotrek vans and quickly replaced with the current configuration of a switch panel for each Ecotrek and no display.

Is it at a dealer or is it a private sale?

Are there pictures online?

There were so few of these that Roadtrek may be the only source of info.

The 6 year RT warranty became available on units purchased 8/1/15 or later. If this unit is covered by the warranty, that should provide some peace of mind on the technology. If not, that should be figured into the price.
