Wireless is not an option, guys, no worries. There's a ridge in the way.
It's too far for coax as well, or so we were told by both the cable co,pony and separately by an engineer friend whose job is getting Internet to fairly remote factories.. Fiber is something we'd considered (and we'd trench it in along the water line, which doesn't run up the driveway and wouldn't cause erosion there). Our friend is willing to consult in it and pointed us to info and products already.
But. From the rough plan we worked out with engineer friend: We'd have to install a shed or something to shelter it all. The mobile home is no longer stable. We'd have to deal with fairly regular break-ins to the shed based on prior break-ins and car stripping down there. We'd have to install solar panels, wire, and converter; there's no power. We'd have to buy the fiber and the conduit (which, yes, would probably be PVC, so pretty cheap) and the converters at both ends to go from copper to fiber and back again. Because the site, and the pole where the cable runs, is on a steep north slope, we'd have to mount the panel(s) on probably a 50-foot pole to get any light on them. If we went back to grid tied power instead, we'd have to reactivate the account down there and pay another monthly base charge or else pay for ~ 900 feet of buried power line from our current transformer at the top of the hill.
We've only done back of the envelope math on this, but the quick and dirty calculations suggested all this would be more expensive than paying for the cable line, maybe much more expensive.
