On two separate bikes, I have lost the right side fork seal within 1 month of purchase. Never have problems with the left side. The worst part is, they have both taken out the fork tube as well (scratched) when they go. What is happening here? Things falling from my garage ceiling? I want to prevent this in the future, and have been keeping my bikes covered when parked, but what am I not considering here? I have never dropped either bike, FWIW.

Is it possible that both fork tubes were scratched already when you purchased them?

Neither leaked at time of purchase, and if there were scratches they weren't deep enough to feel at that time.

Beware the likes of bugs and their shells, leaf particles and other absurd sounding things. These sorts of things can do a dandy job of scratching the chrome tube when they are trapped under the top lip.

Gators can do a lot to help keep them out.

Probably, my zx10 had cut up socks in a setup like that to prevent the fork oil seepage from getting on the brakes/tire. It worked quite well.....until the seals completely went.

That's the opposite side of the kick stand. Has anything fallen on to it? Possibly without you knowing?

More then likely it improper fitting of the front wheel after a tire change. Most modern bikes the axle nut pull the axles shoulder to the left fork tube and pinches it to the tube. then your supposed to Settle the right fork tube by looking the front brake and pushing down hard several times then tighten the nuts holding the right side axle clamp. if the tube is even slightly in or out it wears on the seals and bushings in side the fork tube. also no one cleans the tubes theses days you need to keep'em clean and wipe with ATF then wipe dry with white cloth rag if the ATF wipes gray keep cleaning. Oh those cozzey type wiper have very mixed reviews some claim they trap to much dust and grind away the coatings.

One thing I learned as a KLR owner is to only buy OEM seals. The 'high performance' aftermarket ones reportedly didn't last near as long. Probably not your issue, just throwing it out there.

I had the sme issue the last few years. My wifes bike had two leaking for seals and I had one. all on the left side.

Her second one was probably a bug, it stopped after a short while and when I sent it out to get done, there wasn't that much fluid gone (but a ton on her fairing).

Riding 30 plus years and owning dozens of bikes, the only other time I had forks leak were when my friens "helped" me tie down a dirtbike on a trailer and blew the seals out.
