Kevin,
There was an article on Model Railroad Hobbyist, I believe, in which the author told and demonstrated employing two vertical lift systems in order to gain enough height under a lift out panel for him to stand and work on surrounding scenery. I can’t give you the thread as I have not found it a second time.
Bill Brillinger may be able. to tell how to locate a specific thread on MRH.
The method was straight forward and appeared easy to install. His were television lifts ,also.
