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

Posted on September 16, 2022

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).

Question from Danielle: I have what’s probably a really stupid question.

Question from Teresa: I was visiting my mom the other evening and we decided to sit on her back porch for a while.

We both sat down in metal chairs. Her chair had a cushion on it, but mine didn’t.

My chair was so cold that I couldn’t stand it so I got up and switched to a wooden chair.
