Gorge camping question for veterans

My group, along with a friend’s group, is planning to purchase powered RV camping spots at Grove. One of our other friends, who lives more locally, will be driving in and camping with a rooftop tent on their vehicle.

We noticed that in the regular camping areas, it’s allowed to park a vehicle and camp next to RVs. Can you confirm if this is also allowed in the powered RV camping area? Additionally, would they need to purchase an RV camping pass, or would a regular camping pass suffice?

Our plan is to have two RVs parked in two adjacent RV camping spots, so there should be more than enough space for one or two cars to park within our plot.

Edit we plan to all arrive together we will see if that actually happens or not. Also should ask if there is going to be early arrival camping sold later like arrive on Wednesday
