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.
