One thing I forgot (but another noted) is that you haven't mentioned what your tow vehicle is..
I tow my camper with an '04 F-350 DRW CC PSD 4X4... I've had dualies since '77 and prefer those for towing.. More tires = better load distribution. That also translates into a more stable towing unit. Once you're used to a trailer or camper behind you, making turns in towns or similar gets to be a piece of cake....
If your vehicle is a half-ton, you're going to be limited in camper selection.. A 3/4 is better, but a one-ton (properly equipped with camper package etc.. ) can tow a very large TT or 5er with relative ease..
If you're going to pull a trailer that can gross 12K or larger, you need to research your truck specs and stay within limits.. If it's a diesel, ensure you have an EGT and trans temp gauge - either factory installed options or as added equipment.. Those are the two I watch constantly when towing the 5er..
Best of luck..
