First off, Please forgive my negativity...
Before you start your truck project I think you should go "ReFi" your house and get right around $100K in cash, then stop by the local liquor store and get a large bottle of tequila & 12 pac of Pacificos, then head home.
Once at home, set the beach chairs around the fire pit the get a good fire going. Then invite a few friends over to party around the fire with you while doing the shots of tequila with the beer backs.
THEN START THROWING YOUR $100K of CASH INTO THE FIRE!
Doing that, You will end up financially ahead!
P-19's are dirty (your state will probably not allow you to register it for road use), slow expensive to run junk! The true definition of a "Land Yacht" (a hole on the land you pour money into)!!!
