Towing Requirements

Often the tow vehicle you have determines which trailer we can share with you. In order to tow one of our little teardrop travel trailers, your tow vehicle needs the following:

7pin 7-pin Connector
  1. Tow hitch with adequate capacity for the trailer you are renting - The hitch receiver should be labeled with its tow capacity. Check your hitch and Owner's Manual to ensure that meets the minimum requirements outlined below.
  2. 2" ball - This is a standard size for trailers and boats.  Our trailers tow best (less bounce/drag, better mileage) when the top of the ball is about 16" off the ground.  Outback models are happy 19-20" off the ground.
  3. Electrical Connector - See the table below to determine the connector required for the trailer you are renting.
  4. Liability Insurance - We provide comprehensive and collision insurance on all of our trailers at no charge to our renters. Liability insurance is covered by the policy on your tow vehicle, which typically extends coverage back to anything you tow with the vehicle.

All of our trailers (except The General) are wired to connect to a standard 7-pin connector.  If you are renting a 2014-2017 model trailer, a 7-pin connector is mandatory since they have electronic brakes. The T@G trailers (Nomad and Escape) are wired for a 7-pin connector, but we have an adapter that will let you hook up using a 4-pin connector if needed.  The General is wired for a 4-pin, and can only be towed with vehicles that have a 4-pin connector.

Trailer Dry Weight Ball Brakes Connector Required Vehicle Tow Capacity Vehicle Tow Capacity
Tiki 1780 (Estimate) 2" Electric 7-pin w/12V line > 2000 lbs > 2000 lbs
Outback 1680 2" Electric 7-pin w/12V line > 2000 lbs  
Sofitel 1760 2" Electric 7-pin w/12V line > 2000 lbs > 2000 lbs
Bingalow 1760 2" Electric 7-pin w/12V line > 2000 lbs > 2000 lbs
Nomad 1200 (Estimate) 2" Electric 7-pin or 4-pin > 1500 lbs  
Escape 1095 2" None 7-pin or 4-pin > 1500 lbs > 1500 lbs
The General 700 2" None 4-pin Only > 1000 lbs  

4pinNo 4-pin connector. Only OK on Escape & Nomad, but 7-pin is better.  The General is 4-pin only.

A 4-pin connector handles brake lights and turn signals. The 7-pin adds 3 new wires, but for our trailers we only need one additional wire hooked up, which is the 12 volt battery line. This both provides power to electronic brakes on Tiki and Sofitel, but it also charges the battery while towing all of our trailers.  The T@G XLs (Nomad and Escape) don't need brakes. For these trailers, you can use a 4 pin flat connector, but you will lose the ability to trickle charge the trailer battery from your tow vehicle while towing. We have an adapter that will let you hook these two trailers up using a 4-pin connector if needed.

To Add a 7-pin to your Tow VehicleHere is the 7-pin connector I recommend you install on your vehicle if you don't already have one. The nice thing about this is that you plug in your existing 4-pin to the back of this if you have one, and then wire up the additional 12V line. If you're not handy with electrical/auto work, most auto shops or U-Haul can do this for you for about an hour's worth of work to mount it and run the wiring up to the battery. Now you have both a 4-pin and a 7-pin on the front available. You haven't lost your ability to tow vehicles with the smaller 4-pin flat connector. Nice! If you don't have a 4-pin connector already you can obviously expect the auto shop or U-Haul to have to spend a little more time tapping into the brake, turn signal, and running light lines.

Electric Brakes - Normally your tow vehicle would need to have a brake controller wired in and mounted to your dashboard, which is intrusive, ugly and expensive! To avoid that, we've paid the big bucks and installed the Tekonsha Prodigy RF Trailer Mounted Brake Controller. This means all you need to do is plug the remote controller into a cigarette lighter plug in your vehicle, and you're good to go! There is no need for you to invest in installing an electronic brake controller.


Newer Cars - If you have a brand new car, it is recommended that you do not tow a trailer until your vehicle has been driven at least 2,000 miles to give your motor some time to 'break in' before towing. Towing a trailer places an additional load on your vehicle's engine, transmission, brakes, tires and suspension.  Unless it's an EcoDiesel, then no break-in period is needed!

Wiring and hitch installation: You can print out this PDF and take it to your hitch installer or anyone doing wiring on your tow vehicle to help explain the requirements of our trailers.  It's actually less complicated than they will think, not more!
