Triple Towing: What You Need To Know Before You Pull 2 Trailers Behind A Car, Truck, Or RV

Let’s face it, sometimes you need to be able to pull 2 trailers behind 1 vehicle:

• You might want to tow a toy — like a boat, motorcycle, golf cart and a vehicle behind your RV (like this).
• Or maybe you’d like to tow a camper and a boat behind your vehicle (like this).
• Maybe you have ATVs, bicycles, motorcycles, etc. inside your toy hauler and you’d like to tow it along with ANOTHER trailer to your destination.

The point is… there are times when just one trailer isn’t enough for everything that you want to bring along with you!

Here’s some good news: In many states it is LEGAL to tow 2 trailers at the same time.

In this article you will find out which states allow triple towing, plus everything you need to know before pulling 2 trailers behind 1 vehicle…

U.S. States Where Triple Towing Is Legal

Triple towing IS allowed in the following states:

Exceptions To The RV Towing Laws By State

Of course, nothing is ever straightforward and simple though.

Many of the above states still have a variety of restrictions which could hamper your ability to tow 2 trailers:

Towing Rules For Commercial Trucks vs. Recreational Vehicles

As far as state DMVs go, the world of recreational vehicles and the world of commercial trucking are two separate entities.

Some states allow “double towing,” “triple towing,” or however you wish to label a situation where you have 2 trailers hooked behind one tow vehicle in the commercial truck classifications. But, these rules may not cross over to the RV world!

Commercial triples are set up such that the air brake system continues on through all 3 pieces. And the second trailer rides on a fifth wheel tow dolly — not a 2-inch chrome ball purchased at the local hardware store. Therefore, when commercial trucks apply the brakes, all wheels will apply at the same time with equal pressure.

On the other hand, recreational vehicles may have:

• Air brakes on the motorhome
• Electric brakes on the first trailer
• And, in many cases, no brakes at all on the third item being towed

To that end, the federal D.O.T. doesn’t want any part of regulating non-commercial situations — so, they leave it completely up to each state to set their own limitations for RV towing.

Just remember, seeing a semi truck pulling 2 trailers on or near an interstate highway does NOT mean you’re good to go with more than one trailer behind your motorhome!

Double / Triple Towing Laws By State & By Vehicle

There are 5 great sites that list trailer towing rules and regulations — by state and by vehicle:

1. RV Life Trip Wizard – RV and trailer laws by state
2. World Population Review – trailer towing laws by state
3. Fifth Wheel St – RV size limits, required equipment, and speed limits for each state in the U.S.
4. KBB Towing Capacity Guide – factory tow ratings for vehicles (helpful if you’re towing four wheels down)
5. RV Safety & Education Foundation – weight ratings for pickup trucks including GVWR (gross vehicle weight rating), GCWR (gross combined weight rating), and Maximum Trailer Weight ratings by vehicle

The difference between GVWR and GCWR.

Of course, these resources should only be considered basic guidelines — because laws change and information can get mixed up in translation.

The only way to get completely accurate information about triple towing is to contact the Department of Transportation or Highway Patrol offices for your state and any states you plan to travel through.

If you do tow 2 trailers, be sure to follow all regulations and safety measures — because you will be accepting a whole new level of responsibility with that second trailer. Your ability to maneuver in close spaces (or to stop safely) may be reduced considerably. One thing’s for sure, you can forget about backing up when you’re triple towing — getting everything to turn the way you want in a triple-tow configuration will be next to impossible!
