Need advice for shopping for a car hauler trailer

If you are getting an enclosed trailer. Absolutely get one with the roadside door. I ended up finally putting one in my haulmark. It's a must unless your going to winch in the road vehicles. If you get a great deal on one without it. Figure right at $500 for parts and pieces to put one in yourself and make it look off the lot stock. Not real hard to do, just time and money.
