I rented a nuCamp TAB320 off rvshare.com twice this year. It’s a nice trailer, small, light(er) and teardrop shape, making it more efficient than most other travel trailers.
HOWEVER, I towed it with our Tesla Model Y Long Range. It might be slightly heavier than the iD.4 can handle, and you will want to hook up a harness that can activate the brakes. I haven’t towed with my AWD iD.4 yet, and wasn’t really planning on it, since my experience with the Tesla taught me a ton.
I effectively got 1 mile per percentage of battery with the Model Y. Tried it on two separate occasions in February and March, with outside temps in the 40s and 60s. I used ABRP to plan, even adding extra weight and giving myself an extra fudge factor. Here are some of my takeaways:
1. Plan for no more than 90-100 miles between charging stops. My initial tests going up and down hill had consumption going anywhere from about 500 Wh/mi to over 1000 Wh/mi, going 60-70 mph. My second time renting was for a camping trip to a nearby lake.
Sorry… hit the post button by accident.
on the second trip, I had approximately 115 miles between my home and the lake. Had overall terrain drop of about 1000 feet, but had to go through a canyon pass. I reserved an RV camp site in between as insurance to charge going out and back, just in case. Going out there was great. Had tons of reserve when I got to the camp site.
2. Coming back, even with ABRP planning, I did not forsee a strong headwind of about 30 mph. Uh oh! So going 60 mph was equivalent of going 90 mph. I had to drop my speed to 40, and at some spots, ended doing 25 on an interstate highway with 2 lanes in each direction. I can’t even count the number of times I got flipped off and honked at by truckers for about 40 miles. But in the American southwest, DCFC stations are few and far between. The only spots were a town next to lake that I went to, and the town that I live in, approx 110 miles apart. I barely made it to my RV park reservation site to drop the trailer, head 20 miles into town to fill up at a Supercharger, and go back for the trailer.
3. In concept, pulling a travel trailer sounded awesome: Plug the car in at a campsite or RV park along with the trailer and plan, plan, plan the trip carefully. But I couldn’t forsee mother nature’s surprise 30 MPH headwind the whole way back, going 1,000 up in elevation.
If you happen to live in high-density areas like California or the east coast, hauling a travel trailer with an EV MIGHT
work. But don’t plan on going more than about 70 miles unless you like to live for adventure and don’t mind your wife telling you what an idiot you are for trying this crazy experiment!
4. The TAB 320 is nice. Don’t pull it with full water tanks (I didn’t). I appreciated the trailer’s brakes, and pulling it with the Model Y was awesome. The instant torque made it a breeze to get to highway speeds. But even going downhill, no regen was happening. You re basically pulling a big parachute behind the car. Watch your speed and consumption or you won’t make it to your destination. The Model Y is a slightly more efficient vehicle, but I was really only getting 1 mile per percentage of battery. I don’t expect the iD.4 to do any better.
5. My travel trailer days are done. I had fun with my experiment, but we are still a few years away from this being practical, from a number of charger standpoint and also from battery size/efficiency one. For now, my iD.4 trailer hitch will be for my bike rack. Maybe I’ll get adventurous and decide to hook up a small boat down the road…
