This adjustable hitch is designed for use on trailer or RVs and will work on frame widths of 22 to 68-1/2 inches. I have attached a short video review that you can check out as well. view full answer...
Weight distribution systems are selected based off of tongue weight which is typically between 10% - 15% of your trailer's total weight. Since you're not hauling water your trailer's tongue weight should be between 300 lbs - 400 lbs depending on what's mounted on your tongue. With as light of a trailer as you have their aren't many options for that low of a tongue weight which is probably what has caused your confusion.
With all of this in mind, I recommend the Equal-i-zer Weight Distribution... view full answer...
