What broke my window?

Sounds like a bb or pellet. If that's the case, I'd think you'd find the projectile in between the panes.

Weird.

Looked for that but cant see anything yet. Will look more closely when I replace the window and can take the glass out.

Is it on a side where a mower could throw a rock or other object at it? Maybe even at an RV park while you were away and they were mowing.

VERY strange as I thought RV glass was tempered. Maybe it's set the inside that is as I am now looking at mine and the inner is the only pc that has the tempered bug etched into the glass.

Had two broken windows on my trailer in storage. One was when the trailer was parked between two other trailers blocking the window. I could tell by the break pattern that it was a rock from the lawn mower. It doesn't take much of a rock coming at lawnmower blade speed to go through a window.

Not parked where a mower rock could hit it. On closer examination, it looks like only the outer window is broken. The inner looked shattered, but that is backside of outer window, which looks not shattered on the outside due to dark shaded glass. I suppose it could be a rock but it is a small penetrating hole, more like a pellet

I once was on a long bridge, no traffic going either way. Only me when a rock struck my windshield. No clue where it came from. Space maybe?

I think I'm leaning toward the .177 caliber BB or pellet theory as well. Depending upon distance and velocity, BBs tend to bounce off targets and pellets tend to penetrate targets. Not that it matters, either way, your window is broken. Sad if it was a mischievous act.

When replacing it, you might be able to reveal further evidence of the cause.

Perhaps a slightly related story: Many years ago (early 80's) my mom was driving home from work and she heard something hit the roof as she was approaching a pedestrian overpass on the highway. My dad and I went out to look at the car. Right above the driver's side of the windshield about 6" back on the roof, there was a long, deep gouge in the roof. My dad grabbed a .22 bullet and it fit perfectly in the groove. Split second timing difference and it probably would've hit the windshield and my mom, probably causing a fatal accident at highway speeds. As we looked into it, apparently there were numerous reports of people throwing rocks and bricks off the bridge to hit the cars below as well. They put a "fence cage" all the way around the walkway to prevent objects from being thrown over, but the incidents continued. A few short years later, the walkway was taken down.

Just because we call it "civilization" doesn't mean all of the inhabitants are civilized.

Good Luck,

Our friends had a side window explode on their brand new Thor toy hauler. Thankfully they hired a lawyer as there was a magnitude of other problems but a window did blow out for no reason.

Occasionally. One of those big mowers doing the side of the road lets one get thru. Same for gardeners using a powerful string trimmer or.....some smutz with a BB gun.
