how to shop for small pickup truck
 

I am shopping for used small pickup truck.
I will be using this pickup truck to primarily loading furnitures & appliances to over to our 2nd home, around 80 freeway miles in central California.
We are retired couple. We are thinking to pay no mare than $4000.

We wish to avoid any major enginer or transmission repair.
What pickup truck do you recommend?

Thank you for your help.
