Towing ability for my '96 Camry

Hi. I recently purchased a '96 Toyota Camry, and we are about to move. We are only taking minimal things with us for now, until the movers can bring the rest. We rebuilt the transmission, and the car seems to be running fine now. We (obviously) purchased the vehicle used, and it did not come with an owner's manual. My question is, can we install a tow hitch on the back and tow one of the SMALLEST moving trailers on it? I've seen them as small as 3 feet long, and 5 feet wide. Or, would you recommend we only take what can actually fit in the car? We are moving from 0' elevation (Sea Level) to 7900 feet above sea level! So, we will be going up hill most of the way. Please advise. Thanks.
