It's really impossible to answer this question because there are some key things you have to know to determine what you can tow. What you have to find out is what the GVWR (gross vehicle weight rating) of your vehicle is. Then you subtract the actual weight of your vehicle, and the amount you have left over is the amount of weight you can tow. This seems complicated, but it's something you can figure out in 10 minutes once you know where to go for the info. Go to any RV forum or website and you can read all about how to figure it out. I know this sounds nerdy, but 7,000 lbs of steel hurtling down the interstate deserves a little research. If the numbers come up right, by all means go for it.
