Has anyone figured out how to attach a BOB trailer to a RAD Rover?

I use an insulated battery cover for winter riding here in Vermont, which seems to give the battery a little more stamina in really cold weather..  It also keeps water and dirt off the tray.   Is there any downside to using the insulated cover in warm weather?   It's a bit of a pain to remove/reinstall.   

I was looking for a bag for the large basket I recently mounted on my Rover to use for grocery shopping. The bag on the Rad website seemed a bit pricey, and it isn't insulated (the insulated Rad bags don't fit the basket).  Searching online for "insulated delivery bags" and "soft-side coolers" turned up lots of options in different sizes at different prices. 

I tend to forget to unplug my battery charger.  This $10 timer was the solution — set it for 1-6 hours depending on how much charge you need:  BN-LINK 12 Hour Mechanical Accurate Countdown Tim...

The CURT AUXILIARY LED INDICATOR LIGHTS #53201 are a great safety addition to the Hollywood and other hitch racks, especially if your bike is covered during transport and your vehicle's rear lights are obscured. The lights install quickly and easily without any tools.  A few zip ties help with keeping the wiring tidy.

Has anyone had any luck hitching a BOB trailer to a Radrover?  How did you do it?  Or any luck with any other trailers and hitch systems?
