DATA THREAD: Post your tow and efficiency!

[hturnerfamily]

been towing my 'new' 6x12 enclosed cargo trailer for several weeks over 5 to 6 113 mile trips, each going exceptionally well for this single-axle ~1,500lb dry weight trailer, with ~2,500lb-~3,000lb loaded weight... for a home move...

smooth, easy, and the truck hardly knows it's there... and each trip does not require a charging stop, from 100%, with about 1.4-1.5mi/kwh average... I have a 240v 30amp mobile EVSE at both locations, home, and the 'new' home...

I did, though, stop last evening at a brand new RACE TRAC with a new set of 'DC Fast Chargers', under a roof covering(nice), and with fairly easy access, with the trailer attached - CCS AND NACS. This is basically a rebranded 'Shell' Recharge station, and, unfortunately not a Ford Blue Oval member, and NO 'tap' credit card payment method: you MUST scan the QR code, and 'create an account' with your Payment Method, to even get started - then, you must understand the 'instructions' to start the charge, which took maybe 8 tries since their instructions are NOT clear, as sometimes it alludes to something to do on their 'app' website, and other times it says you must 'check' the screen to proceed, etc... not very intuitive - and seemingly an 'old' software from Shell.

oh well. it could be worse. Once it DID start, it stayed at about 120-140kw for the few minutes I needed to get a few extra miles... @ .56 per kwh. Nice to have an option, but I won't be using this one much, if ever.
I think owners of stations, or their 'brands', don't understand the need for EASY, INTUITIVE, and QUICK charging, for all the money they spend on these locations. Maybe Plug-N-Charge will come, one day...we can only hope.

Not sure if the OP Spreadsheet continues to be updated, but it's helpful to see various results. Just completed my first extended tow, and this thread was helpful. Here is my result:

Trailer - U-Haul 6x12 cargo trailer (double axle)
Efficiency average - Bounced between 1.3 and 1.4 mi/kWh at 65 MPH (same efficiency loaded and unloaded)
Towing miles: 257, mostly interstate
Outdoor Temp: 95 degrees
Notes: Battery temperature would exceed the mid-line at the end of a DCFC, at one point approaching the upper line. Always cooled back down while driving. I have the Max-Tow Package.

I pulled my new travel trailer on my latest trip to Colorado. I didn’t keep track of the Lightning efficiency pulling the trailer. All I really cared about was having enough range to make it to my next charging stop.

8.5x26' Homesteader Intrepid HD car hauler with 7' interior ceiling. Saw roughly 0.7 mi/kWh in absolutely perfect weather with only me in the truck and no camping gear loaded. I estimate it will be in the 0.5 to 0.6 range on an actual trip. Absolutely miserable. It's a shame, because when NOT towing this truck is amazing.

Late to this thread, but wanted to share. We have 3500lb tent (popup) trailer. Probably over 4klbs when loaded with the toys and kids. We get 1.2-1.9 when loaded, and camp ~5 times a year but mostly within range of our SR lightening. On a trip from Crater lake, it was all downhill and we averaged 3 miles per kw for about 300 miles. Love the truck, but admit aerodynamics is everything when pulling a trailer.

Tonight I'm towing my 12' utility trailer on a trip to go pick up some gym equipment. Mostly 55 MPH highways. This trailer is returning 1.9 to 2.0 mi/kWh. Much much better.

Side note: the trailer light check feature is awesome

This is close to what we get towing our teardrop at the lower highway speed limits.

700 mile overnight road trip from Maryland to the White Mountains of New Hampshire.

23 Lariat ER Max Tow / 23 Lance 2075 6800 gvw

averaged .9 mi/kWh up and back with lots of wind and some rain

ABRP for routing w/ live data was awesome until it wasn't. Worked great for several stops then started experiencing some glitches (stopped routing requiring restart while driving, then got to a point where it would miss the charge and try to route me back to previous stop) and had to resort to plan b. Was nice to have a print out of my plan with addresses. Pleasantly surprised at how well Apple maps worked on this trip. Surprised that I ended up preferring it over Google. Also tested RV Life GPS and will stick to using it for planning. Plugshare's trip planner that shows elevation is great for planning. I was able to plan for extra charging at stops just before the steepest parts of the trip. If you can handle it, traveling overnight is awesome because you can reach stations you would never be able to get to during the day and you can take naps along the way. Lastly, I was pleasantly surprised to run into other EV trucks pulling travel trailers along the way and at the campground.

Happy planning and safe travels!

Trip report:

Richmond Va to Charlottesville Va and back- approx 150 miles and approx 335 feet of elevation gain going. Average temperature of 40 degrees.

Towing a 6x12 single axle utility trailer. Empty weight approx 1500 lbs. Empty going, hauling maybe 200 lbs of cargo back.

100 SOC leaving. Arrival to Cville - 45 % SOC. - 1.0 mi/kwh. 70 mph interstate speed for all but 10 miles.

Obviously, we weren't going to make it back home without a boost.

Took in 35% SOC at EA - 190 kwh charge rate for a bit to get us from 35% to 70%.

Slightly warmer temps coming back got us 1.1 mi / kwh - same 70 mph speed.

First time towing any distance - not that I care since this is not even a regular occurrence and we have 3/4 truck for real towing but a bit shocked such a small load was such a drain.

Hope this helps!

Aerodynamics is the killer, was your trailer v-nose or flat face and what was the height & width of the frontal surface?

FYI - I've learned when towing our teardrop that about 62 - 63 mph is a good breakeven towing speed for our Lightning, apart from other limiting factors such as steady climbs, low temperatures and consistent headwinds. Anything over 65 mph, although of course very attainable with the truck's available power, results in an algorithmic decrease of range efficiency.

We've tested this many times, towing at even steady 90 mph for stretches of road just to compare the range decrease.

Open utility trailer, 2 foot expanded mesh sides and tail gate.

Good 'research' run. Ive got other vehicles for towing so I dont care either way just lower than I expected given the trailer / load

Those tailgates on utility trailers are range killers. At 55mph I get 1.4-1.6 with gate up. Down I will get 2-2.2.

Way over dump trailer (we'll call it 15k+) loaded with crushed asphalt at 55mph i got 1.2-1.3 Big Tex 14LP

23' deep v chris craft lancer on a heavy roller trailer (about 5500 lb) got 1.2 avg 60mph

27' cabin cruiser 10ft wide 11ft tall. 6500-7500lbs. 1.0-1.1 60mph average.

19ft cuddy boat 7 wide 8 tall about 4000 total with trailer. 1.3-1.4 60mph avg.

7500lbs 36 feet long. I get 1.0/kwh while towing at 60 mph.
