Bro,You can tow with the H3, Not a problem. Go to Demco products they will be the least expensive, Blue ox will work but at a higher price for everything.
My setup that i went with is demco tow bar, demco base plates, brake buddy, and brake away switch, also basic tail light plug set up. The manual has the proper procedure to but in nuetual for dinghy tow. I've towed to the Gand canyon not a problem. also one thing the h3 weighs 4700lbs if your m/h is gas its max tow is 5000lbs. if towing with a pusher then the tow capacity is alot higher.

Good luck happy trails.

I am very curious. How on earth do you use a brake buddy on an H3 ?????
I could not think of a more dangerous product to use with the way the H3 braking system is set up. The brake buddy will work on the majority of vehicles, but NOT THE H3. Please do your homework, and find out why.

This is the only & correct way for an H3 braking system. Do not let anyone tell you differently. You have one chance of stopping when you need to. Do it the correct way.

The Unified Tow Brake is designed for use with towed vehicles equipped with vacuum-assist power brakes. The Unified Tow Brake will not function if installed on a towed vehicle without vacuum-assist power brakes.

(The Unified Tow Brake may also be used with towed vehicles equipped with a separate DC pump for Hydro-Boost power brakes (including H3 Hummer).

Thought I would let everyone know the system that I went with and has worked well for over 6000 miles now. Towing system is the blue ox and the braking system designed for H3 and a coach with air ride is the airforce one. This system has worked incredibly well.

OK...FOLKS...Here is what Brake Buddy Says...DO NOT, I REPEAT, DO NOT USE A BRAKE BUDDY on a 2008 H3. I can NOT speak for prior years. The H3 has an ELECTRO-Hydraulic system...NOT the STANDARD Vacuum Assist on Hydraulic System. The Brake Buddy is designed for a Dead (Bled Down) Pedal. The Hummer (H3) Electric Boost is NEVER SHUT DOWN. Therefore, you will LOCK UP THE WHEELS...even is you try to turn the pressure down ALL THE WAY. This is also the system that they Hybrids use (engine is NOT always running...therefore NO continuous Vacuum boost). Going to cost me more $$'s....people suggest the SMGI or other systems...still doing research.

Oh my friends
H3 has electric assist brakes. What I did was relay power to the assist system while also disconnecting power from the H3 power assist and changing to the RV, while also charging the H3 battery . I did this so I would not drain the H3 battery and not leave the key on. I just plug in my towing cord all this happens, its simple wiring and relay. Brake Buddy works fine if you have power assist working which it is. I amazed the folks at Brake Buddy. If anyone is interested PM me and I will send the drawing to show you how.
