Sorry for the long post, but I really wanted to add reasoning to my stance, because it is only my decision for my business, and you need to decide for yourself.
I ran an IT service company for 20 years. We 100% charged travel time as a consultant because it was taking our engineer, who could be billing from a profitable revenue stream closer, where once on site we charged between $175-$250/hr. At $.54/mile, I would always prioritize jobs closer to me which could alienate good, long term clients.
Also depending on where you live, I can travel 70 miles in rural Michigan in less than 60 minutes, or in downtown LA California, you can take 75 minutes to travel 15 miles. I personally disagree with charging clients on the IRS rate. Basically you can take off the IRS rate from taxes, and add in the travel fees as income. The IRS rate is for the vehicle, not the person. What if you brought a VO with you, are you paying them window time or is that free and will be forever?
If you travel 200 miles, and charge $108 for it, that's what the IRS deems is the cost for the vehicle to travel, insurance, maintenance, gas, but you had a person in that vehicle for maybe 3 hours, how is the 3 hours compensated? Something like $40/hr both ways plus the IRS rate for miles. Or come up with a standard, like $60/hr travel all inclusive. You take some risk in case of emergencies, but is easier to sell as a base rate, non-flight service, which could also be non-flight fees for planning, processing, etc.
Now I am talking about midsized companies, not doing a one off real estate photo shoot. But say you got that job 100 miles away, and there is some emergency on the road, a boat exploded on the freeway, and you were stuck for 6 hours, ended up having to get a hotel and almost 2 full days of labor, for $108... That isn't fair to you, nor how most consulting/service companies work. Either they limit their distance, or they charge a fair amount (and often have a limited service area with no fees).
If you had a job, and your boss asked you to drive 2000 miles to a jobsite, taking several days each way, would you only charge him $.54/mile and skip any wage? Or would you expect to be paid for the time you took as well? Apply that to if/when you had employees (not 1099). They would expect their hourly wage for the drive, and where is the revenue for that?
It is all negotiation, if it means getting the job, that is also something really easy to waive as a line item which will get some purchasing agents to sign up, waive it, cut in half, whatever, it will help in negotiations. Once they value your work, you can then say you can no longer waive the fees.
My advice is from 20+ years in IT consulting, managing up to 25 engineers going to client sites from across the street, to completely across the country (overnights charged expenses as well, per diem and hotel fees). If you low ball your fees, then some clients will think you aren't good enough because you don't value your own time.
All above is my opinion, and do what works best for you. But I hope I added enough things to think about to make an informed decision. It is also dependent on what the competition is doing, and I don't mean Craigslist unless that's where you get your jobs from. If you win every job you quote, you are likely way undervaluing your service which is only good to gain market share,
