We are so nice to help you spend all of your money and you have not even pulled into the campground yet.....
Do you have a surge protector going into the main line on your home? Welllll..... you should...... When a EMP hits and fries all of your electrical applications it will cost you thousands and thousand of dollars to replace after about 5-10 years after the grid goes down (never to come back up). Oh, don't worry about that, we will have long been past the stone age period by that time and electricity will be only a faded memory.
You have spent a lot of money on 'stuff'. 25% of it you will use only once during a camping season (and that is because you forced yourself because you bought and 'must' use it). Go camping a time or two and in the mean time research about the different types of surge protectors. The costs and styles and applications very greatly.
Thank-you for letting us spend your money. We like to spend other peoples money, because it makes us feel better because of all of the money that we spent ourselves.
