We have over 3k hours on ours, and if it is hot out we very commonly leave it on for most of the the trip. We just ran from Denver to New Orleans with an overnight at a rest stop and it was not shut off for the full 38 hours.
That said I check the oil and coolant at each full stop and it is fully serviced every 100 hours.
