Very sorry to hear of your situation Mike, and really empathise with it. Up here in Ilfacombe I am looking to sell our wonderful 2015 SE Cali.; camping and so much more as a vehicle!
Unlike the van, my life expectancy now estimated in days or weeks.
Had a deal set up with WBAC/WBAV; then the offer plummeted when the system had its import status (RHD but..) from 2015 as a new vehicle revealed. That's a commercial decision for them and me, but I had told them clearly about this from every angle before they made their original offer. Adam at Barnstaple WBAC really annoying by trying to explain the situation about 15 times, which of course I already knew!! What a bunch of timewasters..
Anyway, on more important matters, I wish you all the best!
