Can I install a motorized TV mount myself?

Verified-purchase reviewers consistently say yes, but with caveats. Retailer reviews of the Monoprice and MOUNT-IT! pull-downs note that the mounts are heavy enough to need two people for the lift onto the wall, and an r/mantelmount installer thread describes the MM815 install as 'a lot of work.' Solo install is possible for the VIVO lift stand and ceiling mount, but anything pulling down over a fireplace benefits from a helper and a stud finder.
