RE: Pull a 5x8 enclosed trailer with a car?
Look at the sticker on the door for the gross vehicle weight. It may also give max towing weight or at least the owners manual for the car will say that.
Anyway, if you do not have the manual, take the car to a weigh station, usually a good truck stop will do nicely and weigh it fully fueled, it may cost you a couple of bucks. Then subtract that weight from the gross weight limit on the sticker and there is what you can safely pull
Now the age comes into mind, mileage wise. I'm capable of pulling 1700lbs with my Ranger, but the thing has 210,000 miles on it and a high bed cap on it and pulling a 1200lb 6x10 can be a struggle in wind
