My 2020 Ram ecoDiesel gets 32 MPG normal driving (highway)and 17 MPG towing my 20’ (6,600 lbs) camper back roads. I expect the same differential when my CyberTruck arrives. Nicely done on the video.
I recently towed a 6 x 12 U-Haul trailer from Central Florida to the DC area with my model Y. I wouldn’t recommend it if you had to do it all the time, but as infrequently as I’ll need to do it, it wasn’t a big deal for me. I supercharged 13 times. Knowing this, I purposely drove through the night to minimize congestion at superchargers. I had a mixed bag of situations… But I never had to disconnect the trailer. Unfortunately I only visited one supercharger that was a pull through which is perfect for trailers.
This is a great episode. I learned a lot on how to get the most mileage from my EV, and that traveling the backroads has a lot of advantages to the freeways. The journey is the adventure, not just the destination. Next trip I take I'll avoid the freeways as much as possible.
I towed a very small trailer with my model 3, the slow max speed of towing in the UK gave me longer range than normal. The extra weight doesn't seem to change the range that much. Also overtaking two cars and a lorry (semi) on a long straight was fun with the instant torque. I wondered what they thought as the trailer and car zoomed past.
Rivian is building their own network and so far (a very limited set) they have at least one trailer ready stall. We saw such an installation in Inyokern, California, in the same parking lot with the Tesla superchargers. The superchargers also have one trailer ready spot and we were happy to use it.
The going slow, taking back roads and maximizing the amount of momentum you have is the thing I do now
I love how concerned Jesse was about blocking all of the stalls...so sweet.😊
Just another GREAT video! Awesome job Zac and Jesse and the team!
Thanks guys. The back roads are great. No need to be in a rush to get places
Excellent video! You really covered all the possibilities well. A huge factor when towing a high-drag trailer like that is prevailing wind direction. You can't change it.... but consider it in your range (10mph tailwind vs 10mph headwind is like going 20mph slower! ) - For quick trailer disconnects - an electric jack / trailers that don't have load distribution setups / and I'm hoping Tesla's auto-summon feature will help me move the Cybertruck into the hitch easily, on my own! Now... we could have software to enable charging while moving - and you equip your trailer with 10 or 20KW battery packs... that would be a game changer! (I know there's going to be self-propelling trailers - but that will be a very expensive proposition / vs retrofitting and existing camper)
I honestly had that thought about back roads a few days ago. My Dad always drove back roads. Almost never interstate. There is probably something to it.
One of the best episodes you have ever done. Very informative and objective
Yes, speed has actually more impact on range than weight, so by drivng slower when pulling a trailer can give the same range as regular driving, it only costs time.
In EU 🇪🇺 trailering (cars as well as big rigs 🚛) are limited to 80 km/h. It saves vast amounts of energy to go 80-85 versus the 110-120 you guys did.
I hate odd numbers, but my wife found that 57 mph seemed to be the best speed pulling our 19’ camper. My Model X did really well. There was twice out west when the highway was 80 mph we almost got rear ended by semi trucks. It was scary.
Thanks for doing this! Knowing these details about how different conditions will impact range, I'm sure one day will come in handy. I do wonder how a pop up trailer might do in terms of improved efficiency. As you mentioned, there are many many variables but getting more data on different shapes and size trailers will help fill in the knowledge gaps and get us to a place where we have a better idea of what to expect.
You know what would be cool... A lightweight "aerodynamics maximizing adapter" that would span the gap between the truck's cab and the top of the camper. I wonder how much that would affect turbulence and could it help to make towing a camper more efficient? I'd love it if you guys could try building something like that. Maybe something with a very simple curve through the length of the span would work... Anyhow, great episode!
There is a lot of misinformation about the 50A service travel trailers use. The 50A service for RVs is exactly the same as the 50A service now required for electric stoves in houses. It has two separate 110v legs that are able to be used together for 220v. This 220v is different from 220v in Europe because of the way that they handle the neutral. When you feed your RV with a 50A service you are providing your RV with two separate 110v legs that are kept separate by the RV unless your RV is set up for only a 30A 110v setup. If you use a 50A to 30A adapter, the 30A adapter only feeds 110v out at an unknown current (likely 30A). On another point, if you slow down to get improved mileage for pulling a trailer you still cannot compare it to the mileage you get without a trailer. Wind resistance varies as a square function. If you double your speed, you essentially quadruple the resistance to air flow. If you drove your EV at a slower speed on the freeway, you could improve your mileage considerably by slowing down with or without a trailer. Thanks for the information... there is a big learning curve to pulling a trailer. One more thing -- I notice you are using a load leveler system. It basically unloads the rear wheels of the pulling vehicle by adding load to the front wheels. When I pull my trailer with my diesel dually truck, I don't need the load leveler because the truck itself is pretty heavy. I'm anticipating that my cybertruck will not need a leveling system and I would be surprised if there wasn't something in the Rivian that reduces the need for that device as well. EVs are a lot heavier than traditional vehicles so it kind of acts like my heavy ICE truck. Hookups would be far simpler without the load leveler and can be done far faster. You could also speed your hookup time by adding an electric jack in the place of the crank type. (It is also a lot easier on an older person in the heat and humidity we see on the East Coast). Keep up the good work. I love your banter.
For the cost of that DC fast charge session, you may have been able to stop and get an RV 50A -> 30A adapter at a RV shop, or even Walmart has them. Most RVs now have a 50A plug, and many Older RV parks only have a 30A plug, so that adapter is super common and safe.
You guys are having too much fun testing out this review you guys have one of the best jobs in a while keep up the good work thanks for all your reviews🎉👍😎
