  • The trucking industry has a very long tail when it comes to equipment. Big trucking companies (100 plus trucks) generally replace their equipment every 3 to 5 years. Smaller companies (10 to 100 trucks) often buy a mix of new and used equipment with an average age somewhere in the 5 to 10 year old range. Then you have the majority of the trucking industry who buy whatever makes financial sense to them at that moment in time and then run it till they can no longer get parts or they hang up the keys. The latter being more common.

    As I was writing this a cab over Kenworth drove by the dock I’m currently parked at. They haven’t been made since the late 80’s, I think. Once the tech is available, then a 10 to 20 year time frame makes sense and will see some 90% to 98% of the old trucks replaced.










  • The EGR and DPF systems used in diesel trucks cause (or caused, it’s been a while since I last looked it up) a big reduction in fuel mileage. I think it was a 2 or 3 MPG reduction.Doesn’t sound like much, but it adds up when you are running 200,000+ miles a year per truck. With the system running I believe the average fuel mileage for the trucks in our company is around 6 to 8 MPG depending on the route.

    Additionally the systems are expensive as all get out to repair and maintain. When the DPF and DEF systems on my truck went out, the truck was down for 3 months waiting on parts, and from what I heard from our mechanic, the final repair bill was around $15,000USD.

    That said, the fines for bypassing the emission systems are big enough that it’s really not worth it, but some owner operators don’t realize it as many don’t run their trucks like the businesses they are. They just know this is expensive as hell and they can reduce the cost by bypassing them.







  • since I don’t want to pay for SSL certificates to setup https.

    You don’t need to pay for SSL certs anymore, most of the time. You can get them for free from a bunch of different places now. I use Let’s Encrypt. The web server/reverse proxy I use, Caddy is able to automatically get a cert for you, install it, and keep it renewed. The only time you need to pay for a cert is if you are handling financial transactions.

    Are there security issues I should address preemptively?

    WordPress itself has a generally good reputation for security, though depending on how the current drama goes, that may change. WordPress security problems have almost always stemmed from plugins or poor password hygiene. Remove any plugins you are not actively using, keep the ones you are using updated, and use a good password that you don’t use anywhere else. A password wallet like Bit Warden can generate and store such passwords for you.

    Better on the security front would be to evaluate whether you actually need something like WordPress at all. A static site would likely be far more secure. There’s less moving parts that might be vulnerable.

    While you could program a static site yourself, it’s more common nowadays to use a static site generator like Hugo to build the site. You set it up once for how you want the site to look and then you write your posts in markdown or whatever your particular generator uses.

    I don’t have anything to manage my dynamic IP

    Most domain name providers have some sort of setup for dealing with dynamic IP addresses, a program called ddclient is pretty common and is available in most repos.
