The space difference between the EV3 and EV5 is massive, I really can’t see the EV5 being able to hold a hoist smaller than the 3, so I’d start there and expect it to potentially increase.
The EV3 100kg Autochair 4 way Smart Lifter/Apex Assist
The EV5 150kg Apex Assist (mk1) with other adaptions being designed.
Tiggo 8 150kg Apex Assist
Even the Vauxhall Mokka can take a 100kg Apex assist!
