I have a motorhome and needed to tow the H2 behind it. I currently tow a Durango with an 8k lb tow bar set-up. I contacted the mfgr of my tow bar equip and asked them if they would create the brackets for the H2. They said hang on...and 30 days later, whalla, they emailed me they were done.
So if you need to tow yours, here is a link to the bracket kits and tow bar:

The brackets replace/fit into the tow hook area of the frame ends. They are quickly removeable like they weren't there.
Great for towing the H2 with anything that has a 2" receiver.
Will cost you about a grand for the whole set up.
