Towing H3 behind motorhome?

[H3MTA3]

Anyone out there tow their H3 behind a motorhome? I plan on towing mine and would like to know how everyone is hooking it up to their motorhome. The factory towhooks look a little small for the connections of my motorhome. Did anyone have to make a custom bracket or buy one from the dealer or just hook up as is? Any help here would be great!

I know talks manual talks about towing and putting the car in neutral, but I cant imagine that being too good for the trans and t-case. I see heeps all the time being towed behind motorhomes. Maybe this is an F5 question.

it's easy. use the rigging to the tow hooks and you should be fine. lock out the dif and boom. The H2 use to rack up miles being towed if the H3 does as well their is a fuse to pull when towing to prevent. use the anti sway deal so you never have a issue.

I've been on some roadtrips with folks towing their H3's, H2's and H1's. They all had systems like what Big Z linked to.

There's a section in the manual about how to flat-tow. Read it.

I don't know where you guys are getting your information. I have a 2008 H3 Alpha that I tow behind my 43' 2005 MountainAire Diesel pusher. I flat tow and use the brake buddy. I have towed over 9000 this year and have had absolutely no issues what so ever. I installed a Blue Ox base plate kit and use the Blue Ox Aventa tow bar which is rated for 10000 lbs. The reason that I went with the Blue Ox base plate is that it reinforces the frame where many of the others do not. There are two 3/8" thick angle iron braces that bolted to the frame to reinforce the attachment point. There is a 3/16" thick flange plate that attaches to the front of the frame but it is not strong enough or supported well enough to sustain the constant push pull of towing. The reinforing angle irons that attaches behind each flange provides the needed reinforcement. The base plate uses the same bolts that attached the tow hooks. I also used the axuilliary lighting kit which bypasses the hummers electrical system. I didn't want to run any power through the electrical system. The brake and turn signal lights are a single light bulb that is fitted inton the brake light housing. The wiring runs from the aux. bulbs up to the power receptical that is attached to the front bumper. The power comes from the motorhome and runs directly to the light kit. The brake buddy works flawlessly. All you have to do to put the H3 in the tow mode is turn the key to the on mode push and hold the four wheel high button and the four wheel low button simultaniously for about 10 seconds until you see the neutral light. Start the engine put the tranmission in drive to make sure that the transfer case is disengaged, then shut of the engine, put the tranmission in park take the key out attach your tow bar install your brake buddy and go.

AlphaDriver...

ALL I KNOW is that the Tech Support Person that I talked to at Brake Buddy UNEQUIVICALLY said NOT to use my Advantage Brake Buddy Controller (or ANY BRAKE BUDDY SYSTEM) with the 2008 H3 with the Electric Assist Braking system. I also talked to one of the "other" manufacturers and THEY explained that the Electric Assist Braking was "hot wired (Fused)" and ALWAYS on. Therefore, it was NOT possible to regulate the Brake Buddy's controller with the Hummer. There are Horror Stories (maybe they Maladjusted their Brake Buddy) on the other RV forums about Brake Buddy systems (and OTHERS) Locking up the wheels and putting flat spots on the tires...ruining them. I do NOT doubt your success...and I only post this based on what the Tech Support folks at Brake Buddy told me. One of the other systems (Roadmaster?) also has a pressure reducing valve to reduce the pedal pressure. Brake Buddy said that some folks were turning down the pressure on the Brake Buddy, but that would NOT work. I have used my Brake Buddy Advantage for 2 years WITHOUT any problems on my Ford Explorer, however, Brake Buddy said that if I used it on my new Hummer H3, that THEY would NOT be responsible...

The rest of your post is very informative...I decided after researching the baseplates that the Blue Ox is the EASIEST and BEST Base Plate. The Roadmaster requires a Hatchet Job on the skid plate. Your comments about the lighting is also right on...that is why Blue Ox is the way to go.

Thanks,

Need some of the techies to explain this to us...

I have a question (maybe a dumb one). Is there any way to wire into the factory electric assist to apply the brakes?

There is no easy, or for that matter, a practical way to energize the braking system. Brake Buddy has says to call them if you have Elecro-Hydraulic brakes. I have read a LOT about the use of Brake Buddy on the Hummers. Most cite ruined tires, warped rotors, burned out brakes, etc. Sort of like the old adage....That Rattle Snake never bit me until today and I had picked him up a LOT of times.

The US Gear Tow Brake System is the only one that I have found, when looking at the commonly used system, that will properly work on an H3 Hummer.

I have towed my Hummer about 4500 miles now, in all types of terrain and settings. It has worked flawlessly.

Follow the instructions and install it so that ONLY the Service Brake (the MH's FOOT BRAKE" energizes it. If your MH has an Exhaust or Jake or Enginer Retarder Brake, THAT system PROBABLY activates your MH Brake Lights. YOU DO NOT WANT THIS SIGNAL.

You want the Brake Pedal Brake Light SWITCH Signal. US Gear tells you how to find this signal and if you need a Diode. Most Newer MH's are wired or prewired for Braking Systems. The "Brake Signal" is ONLY from the Service Brakes...not the other system.

SMI, a very good vendor, does NOT discuss Electro Hydraulic system...so US Gear is the one that I chose and have not regretted it.
