Short introduction
If you’re towing a pickup truck behind an RV or moving it long-distance without a trailer, a tow dolly is a cost-effective option—but only if matched to your use case. For most users, the answer to "can you go 70 mph with a tow dolly?" is technically yes, but practically no. Most manufacturers recommend staying between 55–65 mph (may vary by model), especially with standard ST-rated tires that cap at 65 mph. If you're asking how to choose a tow dolly for a pickup truck, focus on weight capacity, braking system, and tire rating—not just price.
Front-wheel-drive pickups are ideal for dolly towing; all-wheel or rear-wheel models may require modifications or aren't suitable at all. Avoid using a basic unbraked dolly on highways over 60 mph—it increases stopping distance significantly. If you’re a typical user, you don’t need to overthink this. Stick to 55–60 mph, verify your dolly’s tire speed rating, and prioritize surge brakes for anything beyond local moves.
⚡ Quick Takeaway: What to look for in a tow dolly: minimum 6,000 lb capacity for full-size pickups, highway-rated (LR) tires, integrated surge braking, and tilt-bed design for easier loading.
About Tow Dollies
A tow dolly is a compact, two-wheeled platform that lifts the front wheels of a vehicle off the ground while the rear wheels remain on the pavement. It connects to the tow vehicle via a hitch receiver, typically Class III or IV for pickup trucks. Unlike full trailers, dollies are lighter, cheaper, and easier to store—but they come with trade-offs in stability and control.
They are primarily used for towing front-wheel-drive vehicles, but recent designs now support certain pickup trucks—especially midsize or light-duty models with front-wheel drive configurations. Compatibility depends on wheelbase length, ground clearance, and drivetrain layout. Always confirm whether your pickup can be safely towed in this manner before purchasing.
Why Tow Dollies Are Gaining Popularity
Lately, more RV owners and long-distance movers have turned to tow dollies as fuel-efficient alternatives to enclosed trailers. Over the past year, search interest in lightweight towing solutions has grown, driven by rising fuel costs and demand for DIY relocation options.
Tow dollies weigh less than half of traditional car haulers, improving fuel economy by up to 10–15% compared to full trailers. Their compact size also makes them easier to park and store—critical for RV travelers navigating tight campgrounds. Additionally, newer models now feature tilt decks, surge brakes, and improved coupler locks, addressing earlier concerns about safety and ease of use.
This piece isn’t for keyword collectors. It’s for people who will actually use the product.
If you’re a typical user, you don’t need to overthink this. The real decision isn’t whether dollies work—it’s whether your specific truck and driving pattern make them worth the compromise.
Types and Variants
Different tow dolly designs serve distinct needs. Choosing the right one depends on your pickup’s specs and intended usage frequency.
1. Unbraked Tow Dolly
- Pros: Lower cost (~$1,000–$1,800), lighter weight, simpler maintenance
- Cons: No independent braking; relies entirely on tow vehicle, increasing stopping distance by up to 40%
- Best for: Short-distance moves under 100 miles, low-speed environments
2. Braked Tow Dolly (Surge Brake)
- Pros: Automatic hydraulic brakes activate during deceleration, improving control at higher speeds
- Cons: Heavier, requires brake fluid checks, ~$2,500–$3,500
- Best for: Highway travel, frequent use, heavier pickups
3. Folding/Nestable Design
- Pros: Collapses for storage; ideal for RV owners with limited space
- Cons: Slightly reduced structural rigidity; may require re-tensioning after deployment
- Best for: Occasional users, mobile lifestyles
4. Tilt-Bed vs. Fixed Deck
- Tilt-Bed: Lowers to ground level for easier vehicle roll-on. Reduces risk of scraping pickup bumpers.
- Fixed Deck: Simpler mechanism, slightly more durable over time, but requires ramps.
Key Features and Specifications to Evaluate
When comparing models, focus on these measurable factors—not marketing claims.
Weight Capacity
Must exceed the curb weight of your pickup’s front axle. Full-size pickups often place 60–65% of weight on the front end. For a 7,000 lb truck, expect ~4,200 lbs on the dolly. Choose a rated capacity of at least 5,000–6,000 lbs to allow margin.
When it’s worth caring about: Towing heavy-duty or crew-cab pickups.
When you don’t need to overthink it: Midsize trucks under 5,000 lbs total weight with factory FWD setup.
Tire Type and Speed Rating
Most dollies ship with ST (Special Trailer) tires rated for 65 mph. Exceeding this risks overheating and blowouts. Highway-rated LT (Light Truck) or LR (Load Range E) tires support sustained 70+ mph travel but cost more and may require aftermarket upgrades.
When it’s worth caring about: Interstate travel where speed limits are 70 mph.
When you don’t need to overthink it: Local moves or states enforcing 55 mph towing limits.
Braking System
Unbraked dollies increase stopping distance dramatically. Surge brakes add autonomy and reduce wear on the tow vehicle’s brakes. Required for safe operation above 60 mph.
When it’s worth caring about: Mountainous terrain or high-speed highways.
When you don’t need to overthink it: Flat terrain, short trips, experienced drivers who maintain large following distances.
Hitch Class Compatibility
Requires Class III (2” receiver) minimum; Class IV recommended for full-size pickups. Verify compatibility with your tow vehicle’s frame and weight distribution system.
Pros and Cons
| Pros | Cons |
|---|---|
| ✅ Lower purchase price than trailers | ❌ Not suitable for AWD/4WD pickups without modifications |
| ✅ Lighter weight improves fuel efficiency | ❌ Front tires of towed vehicle still experience wear |
| ✅ Compact storage; some models fold | ❌ Less stable than full trailers at high speeds |
| ✅ Faster setup than loading a trailer | ❌ Limited protection from road debris |
| ✅ Works well for FWD pickups | ❌ May void warranty if drivetrain dragged incorrectly |
How to Choose a Tow Dolly for Pickup Truck
Selecting the right dolly involves matching technical specs to real-world conditions—not just browsing online listings.
Step-by-Step Checklist
- Confirm your pickup is front-wheel drive (FWD). If not, assess if neutral-mode transfer case or driveshaft disconnect is possible.
- Measure wheelbase and track width—ensure dolly accommodates both.
- Check gross vehicle weight and calculate front axle load (typically 60%).
- Select dolly with at least 1,000 lbs above calculated load.
- Determine primary use: local (<60 mph) vs. highway (>65 mph).
- For highway use, insist on surge brakes and LR-rated tires.
- Verify hitch class match between dolly and tow vehicle.
- Test loading process—tilt bed reduces effort and damage risk.
Decision Flow
- If towing occasionally under 100 miles → consider unbraked dolly with tilt deck
- If traveling cross-country regularly → invest in braked, highway-rated model
- If storing in small garage → prioritize folding/nestable design
- If driving in CA, OR, or other regulated states → assume 55 mph max regardless of posted limit
Recommendations by Scenario
- Weekend RVer: U-Haul MVD (rental option) or Weigh Safe TST-5000 with folding design
- Cross-Country Mover: Roadmaster Tow-EZ with surge brakes and LT tires
- Budget User: Generic ST-tire dolly from Alibaba-supplier partners, but upgrade tires before highway use
Red Flags / What to Avoid
- 🚫 Dollies labeled "for cars only" when towing pickups
- 🚫 Missing VIN or certification plate—indicates non-compliant build
- 🚫 Used models with cracked welds or bent frames (common in rental returns)
- 🚫 ST tires if planning consistent 70 mph travel
- 🚫 No parking brake or wheel straps included
If you’re a typical user, you don’t need to overthink this. The safest path is starting conservative: 55–60 mph, braked dolly, verified tire rating.
Price & Market Insights
