Being a fiberglass top, you and a buddy can easily lift it off. The amount of time will vary depending on mounting system (i.e. clamps, j hooks, or bolted to bed)
Had one on my last truck. Could unclamp and stow under the carport in less than 15 min.
Glad to see a shell is finally available, and this is the basic design I want, however, want a little more glass to increase visibility. Went to Leer site, unfortunately this is the only angle photo they have posted.
