We have had 11 (adults/teenagers) in our 2021 Mondo and that was pushing the limits of what we could "comfortably" fit.

G6 is a must in my view, even with the 6 pumps it seems to take quite awhile to fill 100%.

I thought I saw somewhere that the 2022's were only coming with the 7" screen. Notwithstanding, get it! As others have said, this is the only place to see speed, rpm, engine temp, oil pressure, depth, ballast level, and any other vital information. This is not where you want to try to save money.

We have the removable seat back for the sliding seat. it stores under the seat itself, so is not an issue. Bottomline - we used it once, and it did improve comfort for those sitting there, but it really limits movement around the boat.

We also have the rear storage bins - they are good for throwing wet stuff in to keep it out of the boat, but they do make bleeding air from the rear bags a bit more challenging. We now have it figured out, but it took some time. This is a preference thing, but we like them.
