Wes & Steve,
Welcome to HH!
Gary runs a great site and the folks here will do what they can to encourage you and answer the questions you have.

Wes,
What capabilities or limits do you have in terms of mobility?
Your vehicle can make a great blind.
You could easily use a revolver or a single-shot pistol hunting from a vehicle.
If you are right-handed it may be easier to sit in the passenger seat. It all depends how you park and the direction you will most likely shoot.
