Parts Needed to Flat Tow a 2010 Hummer H3 Behind a Motor Home with Aventa Tow Bar


What is the required base plate for Blue Ox Aventa II 10,000 lb tow bar?


Helpful Expert Reply:

I checked with Blue Ox and you can use base plates # BX4104 for your 2010 Hummer H3. It will be compatible with your Aventa tow bar. If you do not already have safety cables you can use # BX88197.

For lighting you can use a simple magnetic kit such as # RM-2120. Or for a more permanent solution you can use diode kit # RM-154.

And finally, most states now require supplemental braking on the vehicle being flat towed. One of the preferred systems for our installers is the SMI Stay-IN-Play DUO proportional system, # SM99251. It will apply the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles.

If you go with the diode kit for lighting then for the braking system to work properly you will also need brake light relay # RM-88400. The relay is not needed if you use the magnetic kit.
