Although F3 and RT models share some parts, they are not the same. We have owned F3-S, F3-T and F3-L models. The F3-S models (both were 2015 vintage) didn't have an air bag booster in the suspension as there was opportunity to easily access the coil over shock, although the standard shock was non-adjustable. The 2018 F3-T has a manual air bag booster with the Schraeder valve under the passenger seat. The F3-L models (2018 and 2023) both had auto leveling via an on-board air pump and no Schraeder valve under the seat.
Ps: I just searched the 2018 Owners Manual .pdf and was not able to locate any reference to the suspension adjustment.
