Some sites are smaller than others. I would read the specs of each site before booking. The best sites (in my opinion) are in Pirate Cove loop. We are in 38 PCOV right now and love it! Water views on both sides.

There are some pull thru sites that can accommodate big rigs. Look at the site map and the camp hosts are really nice and can get you a reservation that fits you.

Definitely, but some better than others. If you reserve through Recreation.gov you can get site details including pad length. I find these to be generally accurate. All of the sites have a concrete "landing pad", generally around 25ft, with asphalt before/after. Depending on asphalt before/after concrete pad you may/may not need to level up long (>30ft) rigs.

Yes but you will have to check which sites within the campground can handle a setup like that. I recommend calling them to be sure. They’re very helpful.
