The most important first concideration is how comfortable do you think you will be driving the big machine. Ive heard horror stories of people making the big purchase, climbing behind the wheel, and taking their first trip almost petrified with fear, and imediately selling at a loss. Thats an extreme and rare. If you enjoy driving something very special, than you can't do better than a Prevost. Full driving skills can be learned, even though some of us never get it 100% of the time. As far as living and expenses the above posts have covered that very adequately. Come to OKC and you'll be hooked.
