Frank, if you're just going to use the tractor on your property the only time you'd need a trailer for the tractor is possible service/maintenance. Might want to check with that local dealer and see what he'd charge to come pick up, and return the tractor when needing his service. If it's a reasonable fee, it would be cheaper than purchasing a trailer. The trailer requires purchase, tire upkeep, taxes, space, etc. Cheaper to hire the hauling!
Find out the service your friend did, when, etc. Chances are you won't need any dealer service for a couple of years, at least. If your mechanically inclined at all, you can do most anything required. And, it you hang out here once in a while you can ask any question and usually get a quick straight forward answer.
You'll enjoy the property and the tractor. I have a brother living in Ft. Collins and my mother use to live in Boulder. Isn't Pagosa Springs WAY down south, and have the warm springs to sooth your weary bones?
