Use the RCO for FSS or check the AF/D to determine if Denver has a phone number for clearance delivery.

Thanks guys! I really appreciate your help. I will use the Durango RCAG frequency to pick up the clearance on the ground tomorrow.
How much does a clearance weigh?
I called them up on the RCAG frequency while holding at runway 03. The communication was loud and clear.How’d it go?
Edit: DRO lists 118.575 as an RCAG frequency for Durango. Don't know how well it works.
But getting a clearance directly from the appropriate ATC facility is always preferred compared to calling FSS and waiting on the line while they having them call the appropriate ATC facility. That's part of the reason the FAA is beginning to publish direct ATC numbers in the AFD and we will probably see FSS relays go away over the next few years.
