Here a couple useful apps and websites that we recommend to our clients
Please note, we're not affiliated with any of these companies. All of the recommended apps are free.
KOA
Campground of America is a huge network of campgrounds. From our clients we've heard that these campgrounds are really nice, and offer an array of amenities. The app is simple to use and lets you locate a KOA campground nearby. You can also filter by the amenities you'd like to have, including wifi, cable TV, pool, propane refill stations and so on.
While the app is good, we especially enjoy their website. It has a really useful "Trip Planner" feature, which allows you to see all KOA campgrounds from your starting point to the end destination.
RV Parky
Helps you locate a place to legally park and sleep in the RV by using your location. Search options include commercial RV Parks, public parks, military only parks, 55 + year old parks, casinos etc. The list also includes stores like Walmart, Camping World and Fuel Stops like Flying J, Pilot etc.
The nice thing about this app is you can also filter by the required amenities, like water, sewer, electric, wifi, pool, allowed pets and so on.
Yelp
This is our most favorite app. While it does not have a comprehensive list of campgrounds or dumping stations, it has something very important, a comprehensive list of places to eat! What is travel if you don't stop by a local restaurant?
The app is very user friendly and allows for a quick search for anything you might possibly need while on the road.
Sanidumps
Even if your particular RV camp site does not offer full hook ups, most campgrounds that accommodate RVs will have a place for you to dump the tanks and fill up clean water. However, if the campground you're staying at does not offer that, Sanidumps is a great app to have. It shows you the places you can dump the tanks nearest you.
Another good option for finding a dump station (not an app) is this website, http://www.rvdumps.com/california-rv-dump-stations-map/
