The world is a great place right now!?
I’m no expert, but it almost appears as though the trailer would be more aerodynamically efficient if it were flipped front to back! Obviously, efficient designs are being looked at…We just did a test towing loop 240 miles total, pulling a Bowlus Terra Firma. We selected that one because it is very streamlined (no bulges, tapered aft) and lightweight. I started at 100% SOC (first time ever, normally 80%) and returned home again with 18% remaining. With 60 miles left to go, we supercharged for 7 minutes, adding 20% battery SOC (25 kWh, $11) to add comfort pad.
Correcting an earlier mistake, this is about 2 miles per percent of battery charge unless I goofed again.
It’s hard to understand why a blunt front is OK. Seems like knife edge on both ends would be better. But they make airplane wings blunt on the front edge and tapered to a point on the trailing edge. Maybe the engineers are just being influenced by that, or maybe math supports it. After all, who would have thought the Cybertruck was a low drag shape? (ok someone did)
Just realized the average energy consumption is almost identical to my bambi 20.My wife and I drove from the Portland, OR area up to Olympic National Park (Forks, WA.). We rented an Airstream Basecamp 16X on Outdoorsy to see how we liked the trailer and how well it performed. The first bummer...the trailer had a huge dent not noted in the listing. No leaks though. Other than that damage, an amazing trailer and a great owner to work with.
First the numbers: 675 Wh/mi was our average over 540 miles at the speed limit and average temp of 70 F. Prior to loading it up with our gear, I got around 500 Wh/mi driving from the renters home to my home 25 miles away. During the trip this meant charging to a max of 80% for time savings giving us up to 96 kWh with a reality of 85 useable kWh to avoid hitting 0 before landing at a SuperCharger. In simple terms, 125 miles between stops. This meant multiple stops per day during the round trip. We could have stitched the run a bit further, but not having experience with the route and trailer, we played it safe.
The experience: The acceleration was unbelievable but the need to charge so frequently took away from our adventure time. We did find a great butcher shop during a charge in Aberdeen and had a nice walk during another.
The attention: As anyone on this forum with a CT knows, you get attention. Throwing the silver streamer behind increased it two fold. Lots of smiles and thumbs up. Even the other campers (only two campsites at this Airbnb property) said they saw us on the road and were excited to be at the same site.
Our plan based on this rental: Skip the Basecamp as it is too heavy and not aerodynamic enough. This also rules out some trailers on our list like the SylvanSport Vast, inTech Sol Horizon and Safari Condo Expedition. Still on our list, The Polydrops P21, Safari Condo A2124, or the power assisted trailers like the upcoming eStream or Pebble.

That’s interesting and a bit surprising!
Another proof that aerodynamic is much more important than the weight itself as soon as it reaches a certain speed.
we almost got the bambi over the BC 20X but the weight difference and more windows in the BC sold us. Weight seems to not be the factor after all, I've found like you did it's aero that mattersJust realized the average energy consumption is almost identical to my bambi 20.

The WC is rated for 48A when on a 60A circuit (80% rule). If you're pulling the full 50A from a 50A circuit for hours at a time, you are overloading it. You should pull 40A max.
We all know this. Thanks.
It's not how you separate the air at the front, it's how you put it back together at the rear that has the greatest effect on your drag coefficient.
