Based on the Equal-i-zer, should I go with 1200 lb bars or 1400 lb bars? Equal-i-zer's web page has a calculator to determine which bars to get. When I plug in my numbers it recommends the 1400 lb bars.
Ditto on getting an accurate tongue weight reading with trailer in a loaded condition. Knowing the tongue weight also helps estimate the number of spacer washers you'll need for initial angle set. I got the Equalizer 1,000/10,000 to pull a 6500 lb. enclosed car trailer with about 750 lbs tongue weight. Took it on a 1000 mile trip with driving rain, strong cross winds and some tight maneuvering in the campgrounds. Worked great. Very stable. No problems at all. Especially liked that I didn't have to remove the WD bars for backing up or tight maneuvering.
