One thing that's always overlooked: You need to look at carrying capacity tag in drivers door jamb, take that number and subtract all people/pets/gear in 'burb, that leaves you with your MAX tongue/hitch weight the burb can support (its always WAY less than the max hitch weights in manual).
Lots more to it than that, just start here. If you have 400+ lbs available after your calculation, you might just be able to pull a small ultra light camper. Report back what kind of weight you have to work with, and we might have more suggestions.
