Just hit 10,000 hours on a 6.7 Powerstroke I've been the only mechanic for

Honestly, I was doing the service on my buddy's 2015 F-250 yesterday and the scan tool showed 10,012 engine hours. I've been the only person to turn a wrench on that truck since he bought it new. Ngl, seeing that number felt pretty good. It made me think about all the little things I've done to keep it running smooth, like sticking to the 5k oil change interval with Rotella T6 and catching a small high-pressure fuel pump weep at around 7,500 hours. The truck still pulls his equipment trailer every day without a hiccup. It's a solid reminder that consistent, careful maintenance really pays off long-term. Has anyone else hit a crazy high hour mark on a rig they've maintained from the start?

I just hit 33,333 miles on my car's odometer and the timing was way too perfect

My $300 portable monitor was a total waste until I got stuck in a hotel with a broken TV

Bought a 15-inch portable screen for video calls and extra workspace. It sat in my bag for months, just adding weight. Then my hotel in Chiang Mai had a TV that only got one fuzzy channel. Hooked the monitor up to my laptop and watched a movie like it was a proper screen. The extra real estate also let me keep my project open while checking emails. Anyone have a better use for these things or should I just sell it?

Showerthought: I used a 3/4 inch crease nail on a draft horse last week and the clinch was way too tight.

I was trying to get a stronger hold on a big hoof, but it actually started to pull the shoe. Now I'm wondering if a thicker nail is ever worth the risk on heavy breeds, or if you should just stick with the standard. What's your go-to for big draft feet?

Unpopular opinion: I think the old-school rubberized lens hoods from the 80s are actually better for impact protection than modern plastic ones.

After a client brought in a vintage Nikon with a cracked plastic hood but a perfectly intact rubber one from the same era, I started checking all my repair logs from the past 6 months and found zero rubber hoods needed replacement, while I'd fixed 14 plastic ones.

Bought a $40 'all weather' phone mount that launched my phone into a puddle the first time it rained.

Showerthought: The aquarium downtown made me think about glass thickness differently

I took my niece to the city aquarium yesterday and stood in front of their big shark tank for a while. It's a huge panel, maybe 30 feet wide, and you can see a tiny curve at the very edges. It hit me that the water pressure must be insane, and the glass has to be way thicker than anything we do in houses. I always just follow the charts for residential stuff, but seeing it in person made the engineering click. Has anyone here ever worked on a big commercial tank like that?

A customer in my shop argued that tire rotations are a waste of money

He said he'd driven for 30 years without one and never had uneven wear. I showed him the inside shoulder wear on his front tires from a neglected alignment. Has anyone else had to convince a customer a basic service is actually worth it?

Showerthought: A talk with a building inspector in Denver changed my whole view on floor flatness

He told me he's seeing a lot of new builds where the subfloor is off by a quarter inch over a 10 foot span, and installers are just trying to float it out. Said it's a ticking time bomb for LVP and laminate, especially with the big temp swings here. Made me realize I need to check flatness before I even unroll the underlayment now. Anyone else started carrying a longer straightedge because of this?

I thought those fancy digital edge finders were just a gimmick until I had to set up 200 identical parts on a VF-2.
