Vegetable Hauling Northern Thailand monomad

I first thought the vegetables in the back of this truck were potatoes. But on a closer look I think they are some other kind of root vegetable instead. Some of them are much larger that a potato would ever grow.

Do you know what these vegetables are?

You can not tell in this edit, but the driver is looking at me as I got busted taking photos of passing traffic. This scene is outside the walls of a resort I was staying in at the time in Northern Thailand. I was there alone before it opened and traffic was mostly my only company.

I am always fascinated by the many different vehicles in SE Asia and how they keep the older ones on the road. I do not think this one is too old, but it is kept up really well for a work truck.

I used a Canon ELPH160 point and shoot camera for this photo. My post today is for the monomad daily contest by @monochromes. You can find a lot of inspiring photography on the daily winner posts over there, so please take a look.
