This is what makes our heavy duty trailer dolly so good.

Why is Trailer Butler electric trailer dolly better than the competition?

It's the little things (that make a big difference)

There are many fine details that go into the design of our heavy duty trailer dolly lineup.  It's the little things that refine your user experience, and we've built around that.  Our trailer dollies effortlessly move up to 12,000 pounds, and automatically control the brakes on your trailer. You control forward and reverse, and our system automatically controls braking.


We also illuminate all outside clearance lights on the trailer while our trailer dolly is in use, providing an extra protection.

Portability

Our trailer dollies become an easily removable fixture of your trailer, just the same as your tongue jack, batteries, and propane tanks are.  When it needs to be used, you simply rotate the Butler into the "control" position, and when you are ready to travel, simply rotate up to the "travel" position.  The  Trailer Butler trailer dolly travels in place, on your trailer, so you can use it anywhere.

Our Design

We have tested most conceivable configurations, both in CAD modeling and prototype testing.  We've tested dual wheel, single wheel, offset, dual drive, single drive, and much more.  The result is what you can purchase from our website.  Our patent(s) pending design(s) offers industry best ease of turning effort , traction, and braking.   The Trailer Butler lineup is second to none on concrete, grass, gravel, rock, curb transitions, and uneven surfaces.

Precision Control of the trailer all the way to the ball of your vehicle.

The frame mount hinged, and frame mount swivel, trailer dollies allow you to "drive" your trailer all the way to the back of your tow vehicle, placing the tongue of the trailer directly over the ball of the tow vehicle.  Because these models do not attach at the trailer coupler, they provide precise control all the way to your tow vehicle.


Weight Related Questions

What is the maximum trailer weight?

Our XHD electric trailer dolly is rated to 12,000 pounds.  The HD model is rated for 7,000 pounds. Please see weights in each product description.  Specific circumstances, terrain type, side slope, etc will determine which model is right for you.

What is the maximum tongue weight of the XHD Trailer dolly?

We offer industry leading 1200 pounds tongue weight with our XHD trailer dolly. The HD trailer dolly line-up is rated for 700 pounds.  Either way, we've got you covered.

What is the additional braking option?

Safety. All of our Butlers come with an automatic brake built into the motor.  If the motor is not in forward/reverse, it automatically brakes.  For those of you with trailer brakes, our electrical control box will also automatically control the brakes on your trailer.  


Electrical Related Questions

I have no electrical experience-Can I install this myself?

Absolutely.  The Trailer Butler is designed to seamlessly tie into your trailer's existing electrical components. All electrical components are pre-wired and color coded.  The only tool you will need is an adjustable wrench (although you can use a socket, box end wrench, etc).  The Butler comes almost ready to use.

What size battery do I need?

For most of you with travel trailers with existing batteries, your existing batteries are generally sufficient (assuming the existing battery matches OEM standards).

The MINIMUM battery requirements are 12 v, 12ah., however we recommend a minimum of 50ah battery (deep cycle). for most trailers.  Failure to use a large enough battery can cause motor failure.

Which type of battery do I need?

The Butler can be used with standard SLA batteries, gel cel, and Lithium (LiFePo4) batteries.  If Lithium batteries will be used, it is suggested to use at least at 80ah battery to avoid issues with the BMS (battery management system).  Deep Cycle batteries are recommended.

Is the Butler waterproof?

The Butler can withstand rain, sprinklers, etc, but should not be submerged.  In the event of submersion, the Butler must be allowed to completely dry out.  It is recommended that the motor be removed, disassembled, cleaned, and re-greased.


The electrical controls (contactor, wireless receiver, etc) are water resistant but should not be submerged.


Installation Related Questions

I have no mechanical experience-Can I install this myself?

Absolutely.  The Trailer Butler was designed specifically so it can be installed by a novice, with very limited tools.  In most cases, the Butler mounting hardware can be installed using only 2 adjustable (crescent) wrenches.

Can I have my Butler installed by a RV Dealer?

Yes, however, we recommend planning this in advance so we can coordinate with your dealer.  

How long will it take me to install?

This will vary based on several factors such as clearances, mechanical aptitude, tools selection, etc.  For your initial installation, plan for about an hour. 

What if I need more assistance?

We do our best to eliminate problems- thats why we ask for your trailer make/model.  Sometimes though, things come up.  In the event there is an issue, you can call or email and we will do our best to get your issue resolved while on the phone.  

The above are general answers. For specific information, please contact us.
