Welcome to the forum Bremar.
I used to have the Zodiac 7-man pro (renamed 420). It's a great RIB at this size. Few things to be aware of. Zodiac say it will take 7 people, but I think the maximum we had on board were 3 adults and 2 kids and that was just about right.
The tubes are Strongan Duotex (Zodiac's brand of PVC). They also slide on a rail on the hull of the boat which is secured at the bow and at the transom. Cleaning is relatively easy when you deflate. No reason to remove the tubes, but new tube set is available but it's damned expensive.
It's a mid V hull not a deep V so will slap in the rough stuff. You can add 25 litres of fuel under the console and another 25 litres in the rear bench seat.
I used to run mine with a Yamaha 40hp 2-stroke and even managed to squeeze a Tohatsu 3.5 auxiliary engine on as a back-up. 50hp would be nice (max hp rating) but the majority I've seen are 40hp.
The 7-man pro used to have a bow roller which was handy for anchor retrieval. The new boats have moved to a grab handle instead. Up front there's a bow locker, fine for storage of ropes and anchor. You can get a bow cushion which adds another seat for low speed cruising.
Zodiac have a pretty extensive accessory list, but be warned, they know how to charge.
Trailer wise, it sits really well on an Indespension set up, and tows very easily.
This is on boatsandoutboards just now. Nice example:
