DATA THREAD: Post your tow and efficiency!

[21st Century Truck]

2023 Tab 320S Boondock
Heght: 8 ft
Weight: ~2350 lb loaded
2022 Lightning Lariat ER

Flat ground efficiency 1.4 mi/kWhr 55mph
Varied/hilly terrain (Montana/Wyoming): 0.9-1.2 mi/kwHr 55mph

Nice teardrop! I love these things.

Thanks, just updated the spreadsheet!

I traded my Flagstaff A-frame camper for a Nucamp T@b 400 last month, but I had a tailwind for the entire trip home. I’ll update next spring when I have some clean numbers, but it’s looking like 1.1-1.2 at 60 MPH. Not as good as I hoped.

I arrived in NH last night after pulling 3,200 miles behind my old Expedition and only averaged 10.7 MPG.

120 kilometers on 54.45 kwh at 95kph, or for those of you living in the past 59 mph, 1.38mi/kwh 3600 pounds of trailer and 'payload' , net elevation gain of zero (round trip) with ~600 meters or 1800 feet of climb and descent

That's a unique rig! Just clarifying.... you went 120kms round trip, and it used a total of 54.45kwh? So, efficiency avg of 45.4kwh/100km?

That's not too bad overall....winter towing, and you'd have a theoretical 300km of range?

I am trying to guestimate my efficiency if I go ahead with a 17ft travel trailer, and upgrade the family from our tent trailer.

It is warm and the speeds were low, YMMV !

I've been towing our GeoPro 19FD for the past two years. It weighs around 4000lbs and is 21' to the hitch. I try to keep my speed to between 55-65 to get 1.2-1.3/ kWh. Speed kills and I see it right away. If I run at 70mph my efficiency drops to 1.0-1.1. In the norther mountains of PA there is still a scarcity of DCFCers so giving up even 10 miles of range to go a little fast might leave me short of getting to a place to charge. All that said, I love this truck and towing with it is smoother and easier than anything I've towed with.

Great, thanks!!

This is very similar to a unit that I am looking to get....around that same length, single axle, etc. And generally speaking i never tow at higher than 65 mph (105kmh), whether I was driving a gas vehicle or EV....i just don't think one should be towing something much faster than that.

So 1 - 1.2 miles/kwh.... is 1.6kms - 1.9kms per kwh...130kwh battery means 208kms to 247kms on a full charge, towing that unit. Mid range....227kms. Gives an efficiency of 57.1 kw/100kms.

That's about the distance I am able to do towing our tent trailer & bikes with my ID4... Kind of wish the truck could tow things a bit further than that, but i guess since I am used to the above distances when towing, i guess it is not the end of the world.

Yep, faster than 65 is too fast for towing at trailer. You don't want to have to slam on the brakes to avoid something at high speeds with 4000lbs pushing you. The only other problem with towing with this truck is it's very easy to forget the trailer is back there. That's how easy it is to tow with this thing.
