Q&A: Why don’t we see used UPS trucks on the highway?

Posted on October 24, 2023

Question from Marvin: For years now I’ve been wanting to get myself a used UPS truck and remodel it into a small RV. Those things are so cool!

The problem I’m having is finding one. I’ve looked at every used car dealership I could find and I’ve never seen even one of them for sale.

And here’s the crazy thing – I’ve never seen a used UPS truck on the highway being used for some other purpose (like my dream RV, for example).

I know you’re pretty good at answering questions so I’m hoping you’ll be able to answer these: [Read more…]

Ever wonder why no one smiled in old photographs?

Posted on March 30, 2023

If you’ve ever looked through a stack of old photographs from the 19th and early 20th century you surely noticed something very odd…

None (or at least very few) of the people in those vintage photos were smiling.

In fact, they all looked like they just lost the winning Powerball ticket.
