I definitely recommend at least one person in your party, possibly two people, bring a tent. Just as an option.
Last year I crashed out in my rideshare's trailer the day we arrived (when my tent was not yet unpacked and we hadn't picked a campsite) and the day before we left, after a decision to delay packing until the sun was less hot, and one last exhausting MOOP sweep. I realize now--since I think about it--that the trailer technically was designed to sleep 6, meaning it may have been the size of your RV. There is a master bedroom (sleeps 2), a couch that folds out into a full-size mattress (2 more), and 2 slightly claustrophobic single bunks clearly aimed at children or the petite. I slept on the fold out couch.
2 people was--of course--easy. 3 would've worked also. At 4 I would've started wanting my own space, but I really love my space in general, so don't mind me.
Would I have been happy as 1 of 6 sleeping inside? No, and most people wouldn't.
Whatever you do--know that when you have 6 people in an RV, you need to allow in advance for the fact that you will probably get on each other's nerves (be happily surprised if you do not
) and the RV is worth more as transport, AC, fridge, and a place for dust-storm shelter and short, careful showers. It is not as great for many people sleeping at varying times. If you anticipate it and pack for it, it won't be so bad. Surprises are much worse.
Exterior shade structures and lounge areas do
help; very smart.
