I'm looking both around Ludlow and around Dover - so Okemo and Mount Snow.

I did this exact thing last time a tenant asked to install a TV mount on the wall of a bedroom.

Things that require security like this add financial risk because construction is like herding cats, And can be filled with time delays that mount up .This is something a more experienced operator might have known to look for, but still read and notate every contract before signing.Good Luck!

My husband and I currently reside in Mount Pleasant, South Carolina.  

Each is about the size of a large plastic container or shopping cart, and they mount right to the wall.

i get one of those mechanical lock boxes from masterlock and mount it to a post or the deck, in the event that the smartlock fails i can get them a phsyical key from the lockbox by giving them that code.

I replaced a broken railing mount for the interior stairs because a guest noticed it was cracked.The bottom line is to setup processes for yourself (or handy person/inspector) to go over your rentals a couple of times a year. 

Are these ground-mount system or roof-mount? 

A bit about the land: it’s in a neighborhood located in a national forest about 40 minutes from a bustling and growing city (Mount Pleasant, SC).

@Nick BrittonRight now the focus is the Mount Snow area in West Dover.
