When I plan an RV trip, the first reservations I make are usually the ones that are hardest to replace. That almost always means national park campgrounds, popular state parks, private resorts in peak season, and anything with very limited site counts. If you are traveling during summer, holiday weekends, spring break, or a big local event, those prime spots can disappear months ahead of time. A regular roadside campground is much easier to find later than a campsite inside or right next to a major destination.
I also book anything that affects the whole route before I worry about the smaller stops. For example, if I need a specific site near a national park for three nights, I will secure that first and then build the rest of the trip around it. The same goes for ferry schedules, special event weekends, or RV parks with strict length limits. If your rig is long or you need full hookups, you should not assume every campground can take you. Sites that fit your setup are the ones to lock down early.
Another good rule is to reserve the “must-have” nights before the “nice-to-have” nights. A must-have night might be the first night after a long drive, a night before an early tour or appointment, or a campsite in a location that is extremely hard to access once you arrive. If you miss those, the whole trip can get messy fast. The flexible nights in between can often be filled later with public land, smaller private parks, or same-week cancellations.
I also like to think about refund policies before I book. If I’m unsure about weather, road conditions, or how far I’ll get each day, I try to choose places with easy cancellation terms. That gives me room to adjust without losing money. It is also smart to check check-in times, generator rules, pet rules, and whether the site is back-in or pull-through. A beautiful campground is not much help if it can’t actually fit your RV or you arrive after quiet hours and have nowhere to stage.
If you are traveling in a busy area, my honest advice is to reserve in this order: hardest-to-get campground first, then any date-sensitive stops, then the sites that need a specific RV size or hookup type, and finally the flexible overnights. That approach keeps the trip from falling apart around the few places you truly cannot replace.
