If you are small enough to fit in one, then it is fine.
Are we talking height or width? I am just a hair under 6'3" tall and have no worries in mine at all. Load it up with bikes, guys, and gear no problems. Drove it for 14hrs with only stops for food and gas. I couldnt do that in my chev half ton, I had to stop because my back was locking up. It all depends on the person.
I drove a '07 Taco when I was buying my Nissan and didnt really like how they felt. It could have just been that one as it was used, or with more time I could have adapted, but to me it just didnt feel right.
