Miller Bar is a river bar that allows DISPERSED camping for up to 14 days. It is about 20 minutes from the town of Brookings. If you take North Bank Chetco River Road all the way down past Loeb Park, it will turn into a gravel road, which is Forest Road 1376. Take the Forest Road down a ways, and you will see a river access sign for Miller Bar. The river access road is WINDING "SWITCHBACKS" WITH SOME STEEP HILLS, which is why only SMALL trailers are recommended. Since parking is directly on the river bed next to the water, camping during winter months with heavy rain is discouraged because of rising water levels and floods. There are vaulted toilets, and that's it, no running water. It is pretty much a "dead zone" for cell phone reception, although with some patience, I was able to find a few spots that I could get service (like 2 bars at the most). I got down there at night when it was dark and didn't see any signs that you had to pay $10 until the next morning when I was leaving. Since it is so secluded, no one even came out there except for locals that were fishing, and there were two other vehicles that were camping also. If you're looking for an "off the grid" peaceful spot to camp out where no one will bother you then this is a great place!
Nice little rest area on Highway 97 North just as you enter Midland. They have restrooms, garbage cans, and drink vending machines (card operated only). There is a Klamath Falls Welcome office (standard hours of operation), and dogs are allowed in designated areas. I have never had any issue with staying overnight and sleeping in my car. It is safe and busier during the day.
Love's Travel Stop is on Highway 97 right next door to Pilot Truck Stop. You can get gas, diesel, and propane here. They have an RV dump station, restrooms and they provide showers, both charge a fee. They also have a coin-operated laundry facility and a small dog park. I haven't had any issue with staying overnight and sleeping in my car. It's safe, and with it being a truckstop, there is always activity. I'm not sure if they have actual hookups for RVs, but they do provide free wifi. The convenience store sells a little bit of everything.
