"It's a completely modififed car... probably based off of a 70s caddy or pontiac. everything has been chopped, that hitch is off a Semi trailer truck, etc. it's not a specific car."
"To me, it appears to be a modified El Camino. But, I could be wrong."
General body shape says it's a Ranchero COMPLETELY modified. The hitch is a fith-wheel off a trailer hauler or possible a big rig. The top is chopped and the body panels are all custom fiberglass. The interior is similar to any late 60's early 70's muscle car. Only the gauges, lights, shifter and wheel are all aftermarket parts you can get from neraly any custom shop.
Oh and the pant's are Levi...
