What your range-loss number means in practice
The percentage is the share of EPA range the trailer eats — and it is set by the trailer and your speed, not by which EV you drive. Two trucks pulling the same camper at the same speed lose the same percentage; the longer-range truck simply has more miles left when it's taken. So read the number twice: subtract the loss from EPA range, then plan legs of about 80% of what remains, because you'll want to be plugged in before dropping under ~20%.
| What you're pulling | Range loss | Ford F-150 Lightning ER320 mi EPA | Chevy Silverado EV RST440 mi EPA |
|---|---|---|---|
| Teardrop camper, 2,000 lb, 60 mph | −24% | ~242 mi | ~333 mi |
| Boat on a trailer, 4,000 lb, 65 mph | −35% | ~209 mi | ~287 mi |
| Open car hauler, 5,000 lb, 65 mph | −39% | ~194 mi | ~267 mi |
| Box travel trailer, 6,000 lb, 65 mph | −49% | ~164 mi | ~226 mi |
| Tall toy hauler, 8,000 lb, 70 mph | −56% | ~140 mi | ~192 mi |
Same range-loss column for both trucks — and for every other EV. Shape and speed set the percentage; the vehicle sets the miles.
A 300-mile towing day, worked through
A Ford F-150 Lightning ER rated at 320 miles, with a 6,000 lb box travel trailer at 65 mph, is estimated at ~164 miles of towing range. Drive 80% of that between plugs and your legs are about 131 miles — so 300 miles takes 2 charge stops, each roughly 41minutes at a DC fast charger that can take the truck from 10% to 80%. That's the real cost of the percentage: not the miles, the stops. A gas truck covers the same day on one tank and a five-minute fill.
Charging times are the manufacturer 10–80% figures for the unladen truck — a trailer costs range, not charging speed, though a stall you can't pull through costs you the time to unhitch.
Which EVs tow a 5,000 lb camper farthest
The five longest-range US electric trucks and SUVs rated to pull 5,000 lb, with the same trailer behind all of them: a mid-profile box travel trailer at 65 mph. Every one of them gives up about 48% of EPA range — identical trailer, identical percentage — so the order is decided entirely by how far each goes unladen.
| Vehicle | EPA range | Max tow | Towing range | Between stops |
|---|---|---|---|---|
| Cadillac Escalade IQ | 460 mi | 8,000 lb | ~240 mi | ~192 mi |
| Lucid Gravity Grand Touring | 450 mi | 6,000 lb | ~235 mi | ~188 mi |
| Chevy Silverado EV RST | 440 mi | 10,000 lb | ~230 mi | ~184 mi |
| Rivian R1S Max | 410 mi | 7,700 lb | ~214 mi | ~171 mi |
| Rivian R1T Max | 410 mi | 11,000 lb | ~214 mi | ~171 mi |

How towing affects EV range
A trailer attacks range in two ways. The big one is aerodynamic drag: a box-shaped travel trailer can triple the frontal area pushing through the air, and because drag rises with the square of speed, that cost explodes on the highway. The second is weight: a heavier rig needs more energy to overcome rolling resistance and to climb grades. On flat ground at 65 mph, aerodynamics usually account for the majority of the loss — which is why a tall, flat-fronted camper costs more range than a heavier but low, open utility trailer.
Put together, most EVs lose 40–55% of EPA rangewith a mid-size travel trailer near their tow rating. That turns a 410-mile Rivian R1T into a ~200-mile tow rig and a 320-mile F-150 Lightning into a ~150-mile one. The percentage is similar to a gas truck's mpg hit, but it bites harder because the starting range is shorter and recharging takes 30–45 minutes instead of five. The practical consequence is planning: you stop more often, and you need DC fast sites that physically fit a truck and trailer.
Range loss by vehicle
Every US EV rated to tow 3,500 lb or more, with an estimated towing range for a mid-profile box travel trailer loaded to 75% of each vehicle's max rating at 65 mph. Unlike the fixed-camper table above, the trailer here scales with the rating — this is the working-near-the-limit case, which is why the loss column varies from row to row. Use the calculator above to model your own trailer and speed.
| Vehicle | EPA range | Max tow | Towing range* | Range loss |
|---|---|---|---|---|
| Tesla Cybertruck LR RWD | 350 mi | 11,000 lb | ~173 mi | −51% |
| Rivian R1T Max | 410 mi | 11,000 lb | ~202 mi | −51% |
| Ford F-150 Lightning ER | 320 mi | 10,000 lb | ~160 mi | −50% |
| Chevy Silverado EV Work Truck | 393 mi | 10,000 lb | ~197 mi | −50% |
| GMC Sierra EV Elevation | 390 mi | 9,500 lb | ~196 mi | −50% |
| Cadillac Escalade IQ | 460 mi | 8,000 lb | ~236 mi | −49% |
| Rivian R1S Max | 410 mi | 7,700 lb | ~211 mi | −49% |
| GMC Hummer EV SUV | 311 mi | 7,500 lb | ~161 mi | −48% |
| Lucid Gravity Grand Touring | 450 mi | 6,000 lb | ~237 mi | −47% |
| BMW iX xDrive50 | 309 mi | 5,500 lb | ~164 mi | −47% |

Tips to maximize EV range while towing
- Slow down.Drag scales with speed squared, so dropping from 70 to 60 mph can recover 15–20% of your towing range. It's the single most effective lever you have.
- Pick the most aerodynamic trailer you can.A low, tapered teardrop or a sleek boat trailer costs a fraction of what a tall box camper does. If you're shopping for a trailer to tow with an EV, frontal area matters more than weight.
- Precondition and charge to 100% before you hook up. Unlike daily driving, towing days are the time to use the full pack. Warm the battery while plugged in so your first leg and your first fast-charge stop both run at full efficiency.
- Plan stops every ~80% of your estimated range. Recharge before you drop below ~20%, and scout DC fast sites with pull-through stalls in advance — many car-oriented stations can't fit a truck and trailer without unhitching.
- Mind tongue weight and tire pressure. Proper tongue-weight distribution keeps the rig stable (and safe), and running tires at the correct towing pressure trims rolling resistance.
- Expect a bigger hit in the cold. Winter towing stacks battery-chemistry losses and cabin heating on top of the aerodynamic penalty. Pad your estimate by another 10–20% below 30°F.
Gear we'd look at
Gear that protects the number above
Nothing on this list adds range — the trailer decides that. These are the four categories that keep you from losing more than the estimate says, or from being stranded by a charging stop a truck-and-trailer can't use. Links go to Amazon search results, not specific listings, and every one of them is optional: check your owner's manual for hitch, wiring, and tongue-weight requirements before buying.
Portable Level 2 charger with NEMA adapters
Turns an RV-park pedestal into an overnight charge
Towing days end with a low pack and start with a full one. A dual-voltage portable with 14-50, TT-30, and 5-15 adapters lets a campground hookup or a shop outlet refill the truck overnight, which is often faster than detouring to a DC site with a trailer attached.

J1772 to NACS (Tesla) adapter
Opens the network with the most pull-through stalls
The hardest part of a towing stop isn't the charge, it's finding a stall you can pull into without unhitching. Superchargers have more pull-through sites than any other US network — an adapter makes them reachable from a Lightning, Silverado EV, or R1T.
Shop on Amazon →
Digital tire inflator with a pressure gauge
Under-inflated tires spend range you already paid for
Towing pressures are usually higher than daily-driving pressures, and both the truck and the trailer drift down over a trip. Rolling resistance is the one loss you can fix in the driveway with a $40 tool — check both before every tow day.

Weight distribution hitch with sway control
For heavy box trailers near the vehicle's rating
Many EVs require weight distribution above a set tongue weight — the manual is the authority. It won't recover range, but it keeps the rig stable at highway speed, which is what makes slowing to 60 mph (the biggest range lever you have) tolerable instead of white-knuckle.

Frequently asked questions
How much range does towing use in an EV?+
Expect to lose 40–55% of your EPA-rated range with a typical box travel trailer at highway speed. A Rivian R1T rated at 410 miles drops to roughly 180–210 miles; an F-150 Lightning rated at 320 miles falls to about 130–160. The loss is mostly aerodynamic, so a low boat trailer or open utility trailer costs far less than a tall, flat-fronted camper of the same weight. Light loads under 3,000 lb at moderate speed can keep you above 70% of EPA range.
What does the range-loss percentage actually mean for my trip?+
It's the share of EPA range the trailer eats, and it's set by the trailer and the speed rather than by which EV you drive — the vehicle only decides how many miles are left once the percentage comes off. Translate it twice. First cut the EPA number by the loss, then plan legs of about 80% of what remains, because you want to be plugged in before dropping under ~20%. A Ford F-150 Lightning ER rated at 320 miles falls to roughly 164 with a 6,000 lb box travel trailer at 65 mph — legs of about 131 miles, so 2 charging stops on a 300-mile towing day.
Why does towing cut EV range so much more than gas?+
It cuts gas range too — a gas truck towing near its max often loses half its mpg. The difference is the starting point and the refuel. A gas truck still has 200+ miles of towing range and refuels in five minutes; an EV starts with less range and a DC fast charge from 10–80% takes 30–45 minutes. So the same percentage loss feels much bigger because the absolute towing range is shorter and stops are longer.
Does trailer weight or trailer shape matter more?+
Shape, at highway speed. Aerodynamic drag scales with the square of speed and depends on the trailer's frontal area and how flat its face is. A 7,000 lb enclosed box trailer costs more range than a 9,000 lb open flatbed with a tractor on it, because the box pushes far more air. Weight still matters — it drives rolling resistance and the energy to climb grades — but on flat highway, aerodynamics dominate. This calculator models both, with shape weighted more heavily as speed rises.
How accurate is this estimate?+
It's a planning estimate calibrated to independent road tests (InsideEVs, MotorTrend, TFL Truck, Out of Spec Reviews), which consistently show 45–55% range loss for a mid-size travel trailer near max tow at 65 mph. Your real number depends on wind, terrain, temperature, and tongue weight — cold weather in particular can push losses past what this tool shows. Treat the output as a starting point and pad it with a safety margin, especially in winter.
What's the difference between this and the EV range calculator?+
The EV range calculator models everyday factors — temperature, highway speed, HVAC, payload, and state of charge — for driving without a trailer. This towing calculator isolates the single biggest hit to EV range and breaks it into the two causes that matter when a trailer is attached: aerodynamic drag and weight. Use this one when a trailer is involved and the range calculator for normal driving.
