A friend is on the way to tow the trailer to my mom's house since it is close (7 miles) and the insurance will cover the tow back to my place (25 miles) but I still need to find out the problem. There's no way I'm taking to into the stealership or even a shop. I don't have $3k to drop on this thing. I will do the work myself regardless of what it is. Also the coolant was not low, I topped it off two days ago and check it every so often.
