Need 12V constant power to run Patriot braking system

I'm towing my manual transmission Mini cooper S with my motorhome. The motorhome has a round 6 blade with round center pin type plug. The car has a smaller round plug with 5 pins and a round center pin type plug. I have a power spiral cable which connects between the motorhome and to the Mini.
I've never had a braking system and figured it was time to get "with the program" so I purchased a sit on the drivers floor/push the peddle type system ( Blue Ox patriot ).
I found out today during a "shakedown" drive that the battery in the Mini (brand new a week ago) is not really husky enough to run the Patriot without running it down fairly quickly. This didn't really surprise me as the Mini battery is only 420 CCA.
So now, I need to understand what is the best way to get 12v power into the interior of the mini that's either (1) fed directly from the motorhome and bi-pass the mini electrical system completely to a new 12V socket under the seat, or (2) run a charging line/wire from the motorhome that recharges the Mini battery if I plug into one of the Mini's standard 12V sockets.
Is there a preferred method of the 2 shown above? Has anyone had this issue with a Mini ( not really sure that theres anything unique about a Mini here), if so, how did you solve it?
Any help or suggestion will be appreciated.

I would go with option 2. You need the mini's battery to power the braking system during a break=away event. Question, why is your system actuating so often to run down the mini's battery? My BB only works under hard braking. Do you have it set correctly? Are all the auxiliaries off? Do you need to pull fuses? JM2...

Hi Terry, thanks for taking the time to respond. To answer your question--I was performing the initial install/setup of the Patriot into my mini. I had cut several pieces of 1/4" plywood in different shapes and I was trying them out one at a time. I was also adjusting the unit height by screwing the legs in/out to get it at the correct alignment with the seat and brake peddle.
I have solved my problem as I purchased an TOAD CHARGER online this morning. This kit has everything I need to properly charge the mini battery from the motorhome and will be easy and fun to install!
Thanks again, have a great week! Ron

Sounds like you have it beat. I had a similar situation some time back and did basicly the same thing you are doing and it worked fine. I also have the Blue Ox Patriot.
