There's a lot to consider if you're looking at a diesel-powered vanlife rig. Trust me, I know about this. I've owned several cars and pickups with diesel engines. I've also been driving semi trucks for decades.
Things to consider with diesel include;
Higher initial cost
higher maintenance
The price per gallon is always more
The additional cost of diesel exhaust fluid
Plugging it in during the winter
Who's going to work on itBuck's new van. That's right. Even though I'm still a good 3 years off from spending significant time in anything but a bit rig, I stepped up and purchased a new-to-me van. You'll have to listen for details.
