50 amp to 30 amp & Surge Protector

This is going to sound stupid... but it's honest stupid.. so here goes... I'm originally from Kansas... where we know and help our neighbors and your "word" is all that's needed...Not saying there's no crime... I'm sure there is... but it wasn't until I moved to Florida... that i really even thought about it... seems to be alot of theft here... I always had the attitude that if someone stole something... they obviously needed it more then I did... However i also don't like driving my boat back without trailer lights for one example... After having 2 different adapters stolen from my truck... I finally started locking up the 3rd one... it wasn't till I moved to Florida that I had ever locked my doors or even took the keys out of my car... I'm definitely not in Kansas anymore...
I refuse to be afraid, however I understand I definitely need to be more mindful of certain things....
