My hubby pulled out our little sailboat to check the hitch height before our trip next weekend

What boat do you have? I used to race on SF Bay and thought about maybe a day sailor I could tow around with the EV.

0.9@70mph is pretty darn good. @Rthardison are you planning on any bed topper when/if GM releases it? I'm curious if that improves the mileage any.

No plans for a topper. I do plan to haul paddle boards in the bed at some point. My ICE mileage improved 1 mpg.

I was not taking it easy on this pull. It was late and wanted to get there. This thing is a monster. You can go as fast as you want. Of course, with an efficiency penalty.

Same for me towing camper: 0.9 mi/kWh for 120 miles. What kind of range would that be while towing with 100% charge?

Does the 4WT camera show trailer side and curb when turn signal is on while towing? It didn't for me, but I didn't have time to look for a settings change.

I have not found any settings to show side view with blinker on in the 4WT.

I had 32 miles left on guess-o-meter. 202 miles of range.

I have turned that to alert only. It happened twice while backgin my camper with lights plugged in.

It has also happened to me three times backing up in the driveway or parking lot. Almost violent stops with no car coming at me. I think there was a car nearby each time (parked -not moving). This feature needs some work.

Yes that back up detection braking is very annoying. I turned it to alert only. Seems to hate our road with parked cars. One time I couldn't even get out on the road from my driveay. It kept hammering the brakes thinking parked cars were a hazard. Turned it off and no issue.

Thanks to that, I had no issues backing up trailer without it connected with the detection off.

I researched this and did not find an answer.

For the RST (with adjustible ride height), does it remove the drop to lower ride height in park when you are in Tow Mode?

It would be ridiculous to set the hitch height if this is sitting 2 inches lower when in Park than what the actual tow height is when in Drive.

Anybody towed max weight with a WT or RST as of yet?

I towed my 7000 lb excavator on a 3000 lb trailer for a short trip to storage, 1000 ft up hill from 700ft msl to 800 ft then 2.5 mile down hill followed by 7 miles flat, a lot of regen and got a little over 3 mi/KWH. My up hill trip with bare truck usually gets 1.6 mi/KWH

Here is another towing video. A few points:

• 120 mile loop + 30 miles + 30 miles + performance testing is getting to or past the range of this truck.
• Do performance testing after the range test. I tell my son, “a road trip is not the time to show off 0-60 performance.”
• When you are afraid to get below 20% state of charge, you must adjust expectations.
• You don’t need to charge to 100% on the road. Just charge enough to get to your destination.
• Apparently, Canada charging is dismal (50 kw).

This is a real problem in Canada with the chargers. Petro Canada advertises 350kW stations but from what I have seen on plugshare, all the ones I have seen so far are throttled to 50kW. No clue why, and I don't know why there isn't a class action against them for false advertising especially since they charge by the minute and not by power delivered. Thankfully I have yet to use public infrastructure.

The other day in my WT4 I went 90km with a dump trailer full of construction waste up and down hills doing 109km/h (68mp/h). Weighed in at 7,380kg (16,236lbs) on the scale. When I test drove the truck before buying, I turned around at a weigh scale and the truck came in at 4000kg (8,800lbs) which means I had a 3,380kg (7,436lbs) trailer weight. I started at 80% charge and ended up with 48%, the truck estimated 51%. I think my estimated range when I started out was around 350km (219mi), finished range was 169km (106mi). Energy usage was 63.9kWh, 1.3km/kWh.

There was only a dusting of snow on the highway and if there was any wind, it would have been a tail wind. Stock tires that came with the truck, outside temperature was around -5*C (23*F).

Normally running empty on this drive I would use 15% battery when it's above freezing, 20% below freezing. Towing below freezing used 32% which really wasn't too bad I thought.

The truck towed the trailer as well as my duramax does. Going up the hills the truck was hitting 220kW consumption. Running empty on the way back used less battery but I did have a headwind and an increase in elevation, I didn't check the consumption plus I made a fews stops before hitting the highway.

Is this a WT, LT, or RST?

WT4, just added it to the post

Whoa...
Let's not make an assumption over 3.8 million square miles over localized experiences.

My experiences in Alberta (Canada) last month:

PetroCanada Canmore, Alberta: 180 kW
Electrify Canada, Canmore, Alberta: 120 kW (on a 150 charger) 145 kW (350kW charger) - no pre-conditioning.
Shell Calgary, Alberta Airport: 180kW
Red Deer Electrify Canada (twice): 367 kW, 338 kW

Tesla? U/K... still no NACS adapter despite ordering Sept 27

We towed our camper yesterday and charged at two Tesla superchargers. At the first stop, I plugged in the camper to the Power Base while charging. No apparent impact to charging. We ran a space heater, used the microwave and ate lunch.

Nice! what is your efficiency while towing that? How many pounds is it?

 

[Rthardison]

Since we have no reliable estimate of arrival State Of Charge (SOC) and are constantly doing our own calculations while traveling with our travel trailer, I am consistently coming up with a battery size of 240 kWh as a base for our 4WT. I have been using 210 kWh in my calculations and am constantly underestimating range. When I back calculate actual range to battery size it is 240 kwh.

Additionally, with two cold weather, 30-40F, trips pulling our travel trailer, we are getting 0.7 miles/kwh. As reference, we get 0.9 miles/kwh in warm weather.

 

[Rthardison]

0.7 miles/kWh in cold weather. 6,500 lbs

how many pounds are you pulling?

 

[Rthardison]

how many pounds are you pulling?

6,500. I think aero is a bigger energy consumer than weight.

Absolutely. My Dump trailer is the same way. Its big, tall and square
