We just returned home from our longest trip (1900+ miles) towing our 20’ Airstream Basecamp with our R1T. Here is a quick write up on our experience for anyone interested.

On our first day we drove from Omaha, NE to Laramie, WY and stayed in a campground overnight to charge (50A) Charging through Nebraska along I-80 was uneventful, hitting several Electrify America stations. Through eastern Wyoming we had to use a 50kW charger to top off charge to make it to the campground.

The following day, we experienced a 60 mph headwind (gusts) that affected our efficiency considerably. We slowed down to 55mph to ensure we had enough charge to make it to Rawlins for the next charger. From Rawlins we made it to Rock Springs, WY for the International Airstream Rally. This was a week long event (over 1200 Airstreams!) and we charged at the campground for the week.

Next, we headed for Grand Teton National Park. It was a 200 mile drive with no DC fast chargers en route. We used a Tesla destination charger in Pine Bluffs, WY for a couple hours to get enough charge to make it to the campground in the Tetons, and charged at the campground for the week (50A).

Returning home, we had scheduled 2 overnight campground stays to charge (no DC fast chargers on the first few hundred miles of the route heading back to Nebraska). Upon arriving in Dubois, WY (where we were planning to use a level 2 charger for several hours), we learned that a new 150kW charger had just opened the day before (we were the first customer to use it!), so only needed a 20 minute stop to get enough charge to make it to our campground in Lander, WY. Lander also had a brand new 150kW charger opening the same day. Had these chargers been available prior to us planning our trip home, we would not have needed the overnight campground stay in Lander.

The next day we drove to a Curt Gowdy State Park between Laramie and Cheyenne for another overnight charging stop. The following day we drove back to Omaha using mostly the same chargers along I-80. Being mostly downhill we were able to increase our average speed with plenty of range remaining between charging stops. We experienced hail 3 times in the last 2 days of our return trip home, but fortunately it was pebble sized and caused no damage to either the Airstream or the R1T!

Some trip statistics:
  • 1.24 m/kWh = Efficiency Omaha to Rock Springs (mostly uphill and significant winds). Average speed = 60 mph
  • 1.29 m/kWh = Efficiency Grand Tetons to Omaha (mostly downhill and some light tailwinds). Average Speed = 65mph
  • $194.05 = total cost public charging stops for the trip
  • ~50% = percentage of times needed to drop the trailer to charge
We are getting more comfortable towing with an EV, and learned on this trip we probably can spend a little bit less time charging, be a little less cautious about our towing speed (most of the trip out we didn’t town above 60), and still arrive at the next charger with sufficient charge. We’ll be taking another 1800 mile trip towing to through Colorado and back next month, and will apply the things we learned on this trip. Overall, we had a great time and really enjoyed the experience. As other folks have already mentioned, stopping every couple hours to charge, stretch our legs, use the restroom, and grab a snack has made long trips towing more enjoyable and less fatiguing.


As a side note (for anyone interested in towing with an EV), I wanted to shout out an upcoming event put on by @allelectricfamily in Amana, IA the first weekend in October. Here is a link to the event: https://www.allelectricfamily.com/chargedrally

We attended last year and learned a lot, made some great friends, and are looking forward to attending again this year. For anyone that may follow RV Miles, they coincidentally are hosting a rally at the same location so there will be plenty of RV ‘stuff’ going on!

Super cool to hear it worked out! I can't imagine dropping the trailer ~50% of the time was fun, but I don't know any other way you could tow for 1,900+ miles for a "fuel" cost of less than $200! A fun calculation would be dollars saved per trailer drop for charging purposes...that would help me feel better about spending the time if I knew I was saving $100 by dropping the trailer and charging instead of fueling at a pump.

Separately, my math suggests you averaged around a ~40% drop in efficiency (and thus, range) because of your tow load. Does that sound/feel right? The math I did was ~1.26m/kWh / 2.08m/kWh typical = 60% (2.08m/kWh is roughly 48kWh per 100mi pulled from here: https://www.edmunds.com/car-news/range-test-2022-rivian-r1s-electric-suv.html )

Since you sound pretty plugged into the RV community, are RV manufacturers starting to list coefficient of drag or other efficiency metrics for their trailers? As someone who's contemplating a road trip with a trailer once I get my R1S, I'd like to factor the efficiency of the trailer into my buying decision...

We tow just with ball / hitch ( no weight distribution / sway bars) so dropping and re-hitching is super quick. If you've ever seen the movie "Christmas Story" - imagine my wife timing me like when the Dad does changing his car tire. :) . Our previous tow vehicle was a 2021 Toyota Tundra. We averaged about 10mpg towing at 65. Doing that math for this trip = 190 gallons x $3.75 (avg) / gallon = $712. Not counting campground costs (we would have stayed at 2 to break up the drive anyway) is a savings of (712 - 194) = $518. Divide that by 12 total charging stops = $43 saved per charging stop. :)

And yes, about a 40% hit seems right to me. I'm still amazed how much difference speed makes (wind resistance) in efficiency, especially when towing. Slowing from 65 - 55 (if needed) can get you another 10-15% in range.

I haven't really seen RV manufactures list drag coefficient, but Airstream claims (and has been verified in towing tests) their trailers are up to 30% more fuel efficient than traditional shaped RV's due to the aerodynamic design and lower profile. And the Basecamp is even slightly more efficient than traditional shaped Airstreams (we had a 23' Airstream prior to the Basecamp).

What’s the weight of the trailer?
3500 dry / 4300 GVWR. It's really a lot more about aerodynamics than weight is what I've seen and learned from what others have experienced. We have friends who tow a 30 ft Airstream that weighs about twice what our Basecamp does, and they see only slightly worse towing efficiently, and think that's mostly because their Airstream is 8 1/2 feet wide vs our 7' 10" width.

Thanks. Headed up to Colorado next week with two motorcycles (about 500lbs each) on a flat bed trailer (which itself weighs about 800).

Awesome, hope it goes well! I would think if the bikes are tucked in behind the truck you won't see a huge hit in efficiency!

Fantastic info and results! I have a 20FB, so not as aero as your Basecamp, but I expect it will still be reasonable once we get our R1T. We often tow at 55, which would probably make up the difference.

Did you use an adapter to charge at any TT-30 RV outlets while camping? Or did they all have NEMA 14-50? I bought an adapter for my Tesla mobile connector and have used it a bunch to get 120v/24a, which has been surprisingly useful.

Also happy to see a Limestone towing the AS, as that is currently our front-runner for colour. Forest Green is our second choice.

How do you find towing with only a ball with the trailer full? Our 20FB has GVWR of 5,000 and we are usually at it. Currently we have an Anderson so I was hoping to stop using the WDH chains/plate part but still use the anti-sway ball setup. I think our tongue-weight might be more than yours though - usually around 650lbs - and I think Rivian suggests weight-carrying only up to 500.

We have friends that tow a 22' Caravel with their R1T and they see similar efficiency, and if driving 55 I' sure you will see really good #'s!

We were lucky to have all 50A campground hookups, but do have an (EV specific) 30A adapter to use at campgrounds and have used it successfully on other trips just with the Rivian portable charger.

We think Limestone matches well with 'Aluminum'. and Forest Green was our second choice as well! :)

I've seen it posted (from Rivian) that the max tongue weight for the R1T is 1155 lbs. Our Basecamp is listed about 525 lbs. We initially had an Equalizer WD hitch on our previous 23ft Airstream, but the dealer told us Airstream didn't recommend it for the Basecamp. We tried towing both with and without, and didn't really notice much difference. The weight of the R1T really makes for an incredibly stable towing experience for our sized trailer, even in strong cross winds that we have experienced.

Thanks for all the info! Just got a used 2022 20x Basecamp and can’t wait to get it out.

Awesome, enjoy!!! Perfect setup if you ask me. :)
