Can welding to the van chassis affect the electronics of the van at all?

OKA196 DIY, self contained 4WD MH, 1160W PV, 326Ah of CALB LiFePO4 batteries, 1.3kW inv, 310L water, 350-450L diesel.
My comment would be disconnect battery and have the welding earth secure earth as close as reasonable to where you are welding.
Good luck

I reserve the right to arm bears :)
Also, (and I am sure that you would have thought of it), make sure that your van is not hooked up to the tow vehicle and that any Anderson plug and 12 pin etc are disconnected.
