Description:

I got this as my first car, a nostalgia piece, and a passion  project a couple months ago. Apparently, the first owner's customization thus far was half-baked and confusing, even for local mechanics, and an RV specialist. I just need to get it out of the yard before I sink my wallet with it unknowingly.
5.7LV8. 700R4 trans. 2 Renogy hard solar panels, 4 Super Start Fleet and Heavy Duty undercarriage batteries, working Dometic RV AC in  the roof, a 2000W/4000W inverter, charge controller, voltage converter, Siemens breaker box, and custom wiring and lighting (which  is probably where the problem lies). 2 unconnected  Flojet water pumps mounted to the undercarriage. Needs all fluids flushed and replaced, due to not being driven for a long time. Could be alternator, could be wiring job, could be bad stock connections wherever...all I know is that the solar system works, and before I replaced the 2yo battery and broke a spark plug off trying to remove all of them with improper tools: All lights, the dash, and the horn (briefly) worked. Now, the solar system's displayed voltage dips when I: try to start, try to use the headlight/volume/power seating or door or window buttons or switches, and any of those, plus JUST the BRAKE PEDAL, can turn the door-triggered cabin lights off too.
So confusing. So frustrating. I'd just rather trade for something of similar value to someone willing to come haul it away for me. Preferably something small but strong, like a Kei  truck, or a used EV, like a Nissan Leaf or Mitsubishi i-MiEV. Good years of middle-age VW Beetles, or DIY EV conversions, are also nice.
