Glad I read this thread. Maybe I won't make the same mistake, but who knows. I totally remove my battery as well to keep it charged in the garage and also to reduce the chance of theft since my trailer is in storage.

Without reading through all of the posts, we did this, blew 3 fuses (the 2 40 amp fuses and the one in the radio). Replaced the fuses and all was fine. We were lucky since we drove a 3 hr drive with it like this. (And yes I know that means other things like brakes probably didn't function right so we were very very lucky!!!!)
