My club has been using a 4 wheel 2WD gator for about 20 years and it now has over 6000 hours on the Hobbs meter. It is showing it's age, but still running like a Deere.

The biggest problem with the Gator is the noisy engine making it difficult for the wing walker to get the driver's attention. Other than that it has been a great tow vehicle and general all around workhorse at the club.
