Think your list is pretty spot on, aside from the drive away not being mandatory.
Would add bellows bungee (from club shop) to ensure the roof doesn’t get caught. Matches / lighter for the gas rings as it’s easier than the piezoelectric thing.
Not things to buy, but practice before your first trip:
- roof up / down. Open the windows, either check yourself or get someone to watch the bellows don’t get caught when putting down.
- turning the front seats, especially drivers seat. It’s an art, watch carefully to ensure you dont scratch the plastic
- closing the front blinds. I would recommend a window wrap from club shop but it’s not essential, just easier.
- inside table can be using as a prep space using the supplied strap that goes on the rear headrest. Took me a year to find that one out.
- awning legs. The locking mechanism feels like it will break. It won’t.
Enjoy it all.
