Without the model/length it is hard to say what it is worth. It can be a 2306C, a 2506C, or a 2806C. Look at the NADAGuides pricing and you will get a relative price for all the models. Click on the model you are looking at. The listing also tells what the empty weights are on those models.

You should look up the tow vehicle on
Travel Trailers, Trailer Camping, 5th Wheels, and Trailer how Tos and see what the tow rating is for that vehicle. They have towing guides for every make and model year.
Also, look here for the Hi-Lo brochure and you can see some weight and capacity figures.

Once you have all that information you can put together a proper combination of trailer and tow vehicle.
