We just bought one of the new crew double cab mules and love it! Seating for 6, expandable bed, half door make everyone feel safe, and we bought the bells but not the whistles. Biggest complaint I have is not being able to find a true half-fold windshield. I bought on from the dealer and it has a small flip-up on the bottom.... Oh well.
I am a big guy and I do not feel cramped like I did when I tested the Ranger for what that's worth. Also, some of the dealers we looked at took us through the shop to see what was being worked on and it wasn't mules, so you be the judge for yourself.
Test both and see what you like, we did and selected the mule and I've never looked back!
Big ones line-up, little ones bunch-up
