With its 4 electric motors Rivian claims the R1T has a towing capacity upwards of 11,000lbs. Despite being closer in size to a Ford Ranger or Tacoma, this figure is quite comparable to that of the larger Ford F150. The main concern here is what kind of impact this will have on overall range, especially under a full load. Similar to the results we see on the Model X, its fair to say that range will be cut in at least half.

Long distance towing is not something that anyone should really attempt, unless you have a string of charging stations along your trip. A good solution to this issue would be for Rivian to develop their own specialized trailer that has an additional battery pack that can provide some added juice.

While we still have to wait and see about the R1T's towing capacity, towing with an EV can be very tricky.

Audi towed a 4,000 trailer with an e-tron and it averaged a high 769 watt-hours per mile (Wh/mi), which would make for a low driving range of around 105 miles. Hopefully Rivian has something in place to prevent their range from drastically dropping when towing.

Unsurprisingly, the e-tron's efficiency takes a huge hit when the SUV is pulling a 4000-pound trailer.

What are your thoughts on the Rivian towing a Micro Mini 5th wheel which is 5700 dry and 7,000 GVWR? I realize that it would cut the MPG in half but I think the truck would be relatively easy to quick charge due to the fact that the charging port is in the front of the vehicle. I wonder if adding a 5th wheel would void the warranty on the truck. What are your thoughts--this is one of the lightest 5th wheels on the market and Rivian claims a towing capability of 11,000 lbs.

You are following vehicle specs so what would be the problem As far as charging the plug at the front, rear, or middle does not make a difference on charging speed unless you think the front will reduce problems with charging while having a tow.

I am just thinking that it would be a nightmare to have to unhitch the trailer in order to charge it. Some people are having to unhitch trailers in order to charge some Teslas that have ports near the rear of the vehicle. Rivian wouldn't pose that problem.

According to RJ and/or Charles Sanderson (I forget which) Rivian can tow much more than 11k lbs. They landed on 11k lbs when the battery was reduced to 50% during their tests. Therefore, if towing less than 11k lbs one could probably count on the range reduction to be less than 50% rather than "at least 50%" as postulated in the OP. Of course other factors will still play a roll in range efficiency such as wind speed/direction, elevation change, driving style, etc.

Certainly, but I only see that working for the pull thru style charging stalls (e.g. similar to gas station pump islands). High majority of charging stalls are oriented like parking spots with no drive thru, meaning, pull-in and back out or vice versa. Either way the trailer will be obstructing the parking lot drive lane unless you unhitch or park parallel to the charging port potentially blocking other charging ports.
