No windows?

I had a conversation with a guy this week who was camping in a large cargo trailer. He said he owns a travel trailer, but wanted to bring his motercycle with him, so he put a bed and some other things in his cargo trailer. I'd noticed that he'd made a second door for the trailer, so I asked him about it. It has one window and a spot for an air conditioner. He said it's pretty comfortable and he can blow air through the trailer and out the vent on top.
I'm surprized that he doesn't have any windows. Maybe he didn't want to cut holes in his trailer.
I'm coming to the conclusion that it's not at all uncommon to sleep in a cargo trailer or even outfit one quite nicely for camping, but that in most cases, the trailer is still seen primarily as something to haul cargo, motorcycles, etc.. Actual conversion of a cargo trailer into a camping trailer is much more rare, even if it's not unheard of.
