General camping will do
Your camping pass will be good for ANY. Camping from general and above. The differences are the upgrades like more space fancier showers closer to the venue. Unless your RV is one of the big mansion on wheels it's gonna be good in any area I'm not exactly sure how the "local guides work"but I'm an employee of the Gorge and I know that the camping thing is confusing. And it changes show to show. But generally there are some basic policies that are consistent each show.
Yes just a regular camping will do. Lots and lots of space
Any pass is good, including standard camping.
Just get the standard pass and you will be accommodated with your RV. Just know that what has already been said is true and you get more space with the more money you pay as well as the other perks.
RVs are mixed in with everybody else, not sure it's a different pass
