Just got back from a trip in the Model S from Dallas to Lincoln. First the Wunder Roost bed and breakfast in Roca--8 miles south of Lincoln--installed a 14-50, so if you're traveling to Lincoln consider staying there. Jim and Kay are real nice folks. Other charging places: Arbuckle Adventure RV Park. Davis, OK. Didn't need a reservation. It's a bit hard to find because the GPS doesn't come within two miles of the place. Best way to find it is to go on Highway 7 from Sulpher and then find Kay Starr Trail (GPS works for this). It's where Kay Starr Trail comes closest to Hwy 77. The Chickasaw National Recreational Park would be an alternative, but they were always full. Winfield fairgrounds. Winfield, KS. Note that the GPS directs you to the downtown fairgrounds where there isn't any RV parking. What you do is go west rather than east on Hwy 160, cross the railroad tracks, and it's right there on the south side. Although I didn't check many, it appears that all the 50 amp plugs are on the tarmac and the 30 amp plugs are in the wooded area. No reservation needed. There are many 50 amp sites but I was told that there are a few special events each year where they fill up so phone to make sure you're not traveling on one of those days. (Memorial day wasn't a problem) Milford State Park. This is the nicest location of the three. It also costs $23.50 for a site plus $5 for a car sticker. I went in late at night and the directions on the sign for how to pay after hours were confusing at best. I didn't require a reservation going up, but I did on the way back (Memorial day). When I showed my reservation, the Park lady looked at me like I was from Mars but there were no actual issues. Route taken: Highway 377 to 177 to 77. No Interstate travel required. A very pleasant drive. Tip: When sleeping in the Model S, orient your head to the rear of the car under the cargo shelf. This cuts off the light from the parking lot lights. Problems: Master charger failed. Ranger Rick flew out and replaced the charger at the Wunder Roost. I never actually lost the use of the car, although I was careful with the distances driven for a couple of days. UMC started overheating. This was only a problem on the way back at the last (Davis, OK) charge stop. I had to switch to a different 14-50 (although the one that stopped 15 minutes after starting to charge had charged fine on the way up). The second 14-50 worked fine with no problems (I dialed the amps down to 38 from 40). When I got home the UMC started heating up badly and after I finish writing this up, I'll go down to the service centre and pick up a new one. Details: Panel breaker slightly warm (These were hot at the Davis OK stop) 14-50 receptacle cool 14-50 adapter warm UMC adapter end hot Cable between UMC adapter end and GFI hot GFI hot Cable between GFI and charge port connector cool Charge port connector cool Flat tire. Nail was in the tire (noticed that one tire was down 3 psi--the useless TPMS didn't tell me, of course). Fixed at Graham Tire Shop in Lincoln. Had it been on the road I still would have been okay because I had a jumpstart kit with inflator and a plug kit but as it turned out I didn't have to use either. All in all it was a great trip with plenty of Tesla time, and Telsa service really saved the day. Other than the charging issues (and the nail in the tire) the Model S performed flawlessly.
