As far as storage it has lots of storage. The port side compartment in the bow you can fit in. The side compartments in the fiberglass hold 2 plano boxes each side. Under the flip up seats in the rear hold 3 boxes each. One project this winter is to take out the compartment box under the lid and make a box to hold more then 3. I have enough tackle in the boat to chase salmon in the morning then switch to eyes in the afternoon.
As far as the flip up seats, I love them. Four guys in the boat only 2 seats on the dance floor. Stand up, flip the seats down and start fishing. Lots of room for trolling or casting. As far as fishing with 5 people, I have only trolled with 5 people, 2 times. It was a little tight but very doable. Not bad. One person on bow all the time when trolling. Only threw in one extra seat, so once we start fishing that seat went up into the bow and had the dance floor open.
I can fit (6) tekota 500 in the side compartment locker and 9-10 trolling rods set up for salmon, Mixed bag of magda 30s to tekota 800 rods and reels in bow rod locker. When salmon fishing I run a spread of 12 lines. 3 lines per person in WI. So I always have about 15 rods and reels in boat. With all setups in rod lockers.
Dont have suspension seats. Do you need them. Of course you can have them. Any boat would be better with them. They would be great. No need just have to slow it down without. But I have been spending my money on rods and reels and one more hds 9. Any more questions just ask.
Good Luck
