Perhaps the previous owner didn't care for his wife much,or had a LOT of children and that title actually says 'SPOUCE car'?
Sounds like motor home would be the best way to get it insured, since from what I understand anything bigger than a 1 ton truck seems to throw up a big red flag with insurance companies.. unless it's an RV.
I guess they figure if it's an RV you probably won't be driving it all that much, and less likely to load the back full of torque converters and go blastin' down the road with a rotten wood bed and soft brakes.
I knew an old scrap guy who gutted a 20 some odd foot Winnebego motor home and used it to haul all sorts of stuff. Since it was a motor home, he could blow past weigh scales and what not.
