As far as being gone from home alot that will depend almost entirely on whether or not you commute.

For an example I work at a regional and have not gotten lower than my 3rd pick bidding and yet I typically leave my house at 4:00am on day one to catch a 6am to commute and then I am gone for day two and three and then I walk in my door on the 4th day anywhere between 4:00pm and 5:00am the next day if I miss all commute and am lucky enough for it to be a night that Fedex is running. For the most part though I typically am gone 4 days and 3 nights of every week.
