That would be my choice too, but the CEO of the house thinks camping is a Super 8 motel.Or this... it's folds up, takes little space, has no effect on range and no problems charging the car:

How have you felt about your pace? Obviously it was well planned in advance, but I'm curious about the reality of it. I could see it feeling slow with an itch to speed up, or also freeing you from thinking about speed since you've got hard limits anyway. So maybe it's more relaxing.I'm sitting at the Butte, Montana supercharger right at the moment after driving 40 miles from Deer Lodge with a 1000 ft elevation gain (to 5530+ft). Energy use at 55 mph was 706 wh/m which was significantly higher than the flatter land 575 wh/m the previous day. Brilliant conclusion of the day: elevation gain affects energy use. We are onward to Bozeman (81miles) in a few minutes.
I must admit that those 80 mph speed limit signs here in Montana want to make me speed up! However, we are moving along at a brisk 55 mph these days.How have you felt about your pace?

Today's numbers: 36.7 miles from Livingston, MT to Big Timber supercharger at 60 mph used 618 wh/m. (400 ft elevation loss)
Big Timber to Billings 82.2 miles at 55 mph used 549 wh/m. Total distance was 119.8 miles. My experiment with speed and similar terrain showed that 60 mph used roughly 69 wh/m more than going 55 mph. Thus a 9% speed increase yielded a 12.5% increase in energy use per mile.
Total energy use today was 68.3 kWh for the 119.8 miles. If you assume a total of 81 kWh available then possible mileage on a charge was 142 miles.
We stopped in at an Ace hardware store in Billings today to get some screws and brackets to fix a few issues in the trailer. My wife opened a falcon winged door to get her camera (to take a photo of the biggest pile of sugar beets we had ever seen by the sugar factory) and out of the store came 5 employees eager to know about the car. We had a good 2 minute conversation including talking Billings supercharger and we could tell that this made an impression on them. We also talked X to a state park ranger as we toured the Pictograph Caves state park. For us this trip is in major part about being ev evangelists, as well as collecting and disseminating data about our X and towing.Hi, Jim,
I admire the journey you are making and the opportunities you are taking to educate everyone along the way and here in the forum about the practical reality of Model X for towing and the general abilities of Teslas and EVs. I feel strongly that the visible example you're setting at RV parks, Superchargers and along the trip are doing a world of good to get "ordinary" people thinking about the virtues of electrified transportation. I'm sure you're opening many eyes!
One question: I notice that you are making a lot of "extra" charging stops because of the energy required to move the trailer and to change elevation. Do you find these extra stops at all frustrating? Or is it a natural part of the way you would like to be doing your trip anyway?
Thanks,
Alan
We have not noticed any battery deterioration at this point. When we get home in two months or so, we will back off to the standard 90% charge.These data are great!!! Thanks for the update
Couple of questions.
Have you noticed any obvious deterioration of the total battery capacity especially since you are charging to 100% frequently?
Do you think the total wh/m takes account for the HVAC, electronics, usb, 12v usage, etc. or just the drive motors?
Do you think there is a significant watt loss when the car is parked?
Thanks for your work
More data - mountain pass edition. Lookout mountain pass (4725 feet) was wild - I watched as our energy consumption rate skyrocketed as we ascended - it topped out at 1735 wh/m ( 1 3/4 KW per mile) near the top. We had just charged at the campground we stayed at and 20 miles later we had 35 miles of remaining charge at the top of the pass. Thank goodness and Tesla for good regenerative braking. We ended our travels in Missoula having gone 121.6 miles, using 73.4 KWh at 604 wh/m. We will be here for a few days visiting family, then it is onward through Montana, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, Utah, Nevada, and California. Data galore to come.
I think this is true regardless of towing. Now that we're starting to see cooler weather here in Northern California, my wh/m is going down significantly.I need more testing of my hypothesis that using the A/C greatly increases wh/m
We had a great time with the RV salespeople in Cheyenne. They were far more interested in the Airstream than in the Tesla, and one of them had just been on a tour of the Airstream factory. They were more than happy to watch our rig while we went to have lunch in the mall.When we were in Cheyenne in May, the RV show was in the next aisle which pushed the mall parking into the adjacent aisles. It may make maneuvering with a trailer more complicated. It should be interesting to talk with the RV sales people.
