16 ft V sounds like the way to go for what want. Just paint it up camo. There are plenty of ideas to make it into a blind if you'd like. Make sure you have enough power a 20 or a bit better would be good but don't go too crazy.
Do yourself a favor , invest in a trailer. My first 7 years or so I went cartop and later pickup bed. A trailer makes it so much easier especially at the end of a long day on the water.
