We just got a 174BH so it is lighter than most but, after researching the reviews on Amazon, I bought this one, a Husky:
There was some effort getting it set up but find it very stable so far. There is also a learning curve on getting it hooked up and removed but it is much easier now. It combines the sway control and hitch in one. Might not work for everyone but it was reasonably priced and has worked well for us, so far.
