We had an Equalizer on our ROO 23SS HTT - towed with our F150 CC with factory tow package, camper was 5000# on the nose completely outfitted for camping. DH loved everything about it except the noise....and it is noisy. We recently moved to a Rockwood Ultra Lite 2604 TT and the dealer recommended the Blue Ox 1000. DH took a look at their online videos and saw a lot he liked, so we went with that. No noise, a snap to set up, works like a dream. Rocky hasn't been to get weighed yet, but tows like a dream.
If you don't feel 110% comfortable about sway or no sway, you need to make the investment. It just takes one time. And IMHO, this isn't the time when you step over a dollar to pick up a dime. Be safe.
