Superglide killed my inner child! Slider or Sidewinder?

Last summer I took my Weekend Warrior LE3305 camping in the Jemez Mountains. Long story short, I forgot to spray WD-40 on my superglide before I came back and it self destructed. The hitch bound and tried to pull the king pin out the top of the hitch. I was stuck on the side of the road with two babies and a pissed off wife for 6 hours. Pullrite was great and sent me a new hitch pretty quickly. The problem is now that I cannot get past the previous failure and a couple of other glaring issues... I adjust the jam nut every time I use the hitch but it starts to clunk about 50 miles down the road. In addition, it uses up every square inch of the bed and even takes a bite of the tail gate every once in a while. So, I am selling the replacement hitch and looking at options...
Given the trailer that I have (which is 102" wide) should I go with the Sidewinder or a standard sliding hitch? Price is not the primary concearn. I just don't want to be stuck on the side of the road with a miserable family again.
