RV delivery is certainly an intriguing business, but I was talking to a recruiter one time and I mentioned I had a family and she got quiet and then said that she wouldn't want to be responsible for me not being able to support my family. She said they prefer retired people simply because they typically do not depend on the work to pay their bills.
If someone is grossing $110,000 doing driveaway work, I assume that means they are driving 147,000 miles or so on the delivery side (which is what you would need at .75 per mile to gross $110,000) and then driving or riding (Greyhound passes are a popular way to deadhead) at least another 147,000 miles to get back. Of course, if there were two truck factories and you somehow got the gig of driving back and forth between the two factories at .75 per mile delivering trucks then you would only have to drive the 147,000 miles, but that's still a lot of miles. I would like to hear more about how this gig gets to $110,000 gross with no waiting for loads and with a reasonable amount of time home. Also, where do you sleep?
Don't get me wrong, though, I would love to hear more. Even a tall tale can be interesting if it's told properly.
