Rule of thumb is stay about 75% or less of the max tow capacity which would put you at 4000lb gross trailer weight. Use your gross vehicle weight rating and max tongue capacity to match.
Generally, but not every time in every case....rear wheel drive tows better than front wheel drive, part time 4wd tows better than AWD, frame on ladder tows better than unibody frame, and V-8 tows better than V-6 and gets about the same mileage towing, longer wheel base tows better than short wheel based vehicles, and ALWAYS double check your tire rating ("D" vs "C"), or better yet "E" rated tires.
There are many trailers (16-18ft) that would match your vehicle fine, but you will pushing your limits with the trailer mentioned, and will not be a pleasant driving experience.
