Narrative: I took my plane up for a few laps around the pattern with a pilot friend of mine and after my second touch and go; I decided to taxi back to the active runway and practice a short-field take off. We were taxiing down the only taxiway at the ZZZ when half way down the taxiway; the plane violently pivoted left toward one of the private hangar homes adjacent to the taxi-way. It felt as if I had taxied into a large hole. I applied full braking and killed the engine. When the plane came to a stop; my friend asked what had happened. I looked out the left window and saw a white pickup truck parked with all 4 wheels on the taxiway. I saw that the last 1/8th of my left wing had collided with the front windshield of the pickup truck. As I examined the damage to the wing; I saw that the wing tip was ripped off and the sheet metal and internal structure of the last 1/8 of the wing was torn and crumpled.ZZZ is a small; private airport and I had used that same taxiway only 20 minutes prior. There was no other traffic using the pattern or moving on the ground. As I taxied; I was looking right down the middle of the taxiway; focusing on staying on centerline. The pickup truck was parked on the taxiway and displayed no warning lights or markers and there were no NOTAMS for taxiway obstructions. The truck was white and blended into the background. After the collision; neither my friend or I knew what we hit. I spoke with the owner of the truck who stated he drove from his house; two houses down; to his friend's house to ask about a part he needed. He said he has just gotten there and walked into his friend's hangar when he heard the strike. There was a little sun glare; but visibility was pretty good.This was an important lesson learned for a pilot with only 180 hours. I followed all the proper procedures:; broadcast on CTAF that I had exited the active and was taxiing; looked down the taxi way for collision dangers; I was taxiing slowly; had all the proper taxi lights on; but just didn't see the truck parked on the side of the taxiway. Always keep your head on a swivel and follow the procedures like it's your first time.
