We added this one to another under bench access. we now have super easy access to all storage areas. This time it took me less than 30 minutes. (The remainder is from my previous install) We decided to improve the access for under bed storage in our Aliner camper. I also made some other modifications while installing these and it took less than two hours to complete the work. I think actual install time for one would have been 30-45 minutes. The only negative I could possible say is these do not come with installation screws/bolts.
