Thanks for all the great advice. I tried all of the possible number combinations, there are 4 numbers in the combination, and also reversing the combination in all of the same possibilities. Just to make sure I didn't make a mistake, I tried all of the combinations again, both forward and reversed. From all the dialing though, the dial now seems to turn a bit harder and sometimes get stuck, temporarily, at certain points. I don't have the proper tools to open up the safe by other means, thus why I was wondering if there was anything else I could do before taking it someplace to be opened. I'm starting to think I'm going to be loading up the safe back onto the truck again. Thanks for the heads up on taking to the locksmith to save some cash.
