Check out the Coachman Apex trailers or the Keystone Bullet. You get a lot of trailer for relatively light weight with these brands. Try to keep your tongue weight (loaded) to around 800 lbs and you should be good to go.
Few more things.
Make sure you air your tires up to MAX PSI on the sidewalls of the tires.. Not the max PSI on the tire loading sticker. That will be about 36 PSI. This is not enough PSI for a comfy tow. You should have a max PSI around 44-50 psi.
Also, make sure you get a good WD (Weight Distributing) hitch.
Thanks!
