The first 15 miles are included, anything after that there is a mileage charge. With that said there is only 1 renter that is any distance away and it happens to be on the way to one of regular work stops, so it works out nicely. Other than that there are many parks locally where it usually goes.
On a side note, we recently did a 1200 mile trip with our MH. On that trip we turned away 3 people looking to rent as it was already booked. 2 of them were repeats, one was a referral.
If I were retired I'd probably buy 2 or 3 more and do more renting.
