I had a 23.5ft "lite" TT, 5000lbs wet on a cat scale, and if I had to do it over I'd have gotten 600lb EQ bars. Honestly if there were 750s or 800s I might have gone that route - and of course there are those sizes in other brands. But not 1000lb bars. The weak point in my setup was the aftermarket receiver and its attachment points on the frame (this was a 1999-generation half-ton GM truck.) Both the truck frame and the receiver were bent after several thousand miles of towing. I then upgraded to a higher rated receiver, and the difference was very significant, even though the receiver I had originally was rated for more than my wet tongue weight or TT weight. It appeared that no further damage was occuring, but I didn't have the rig long enough to know for sure. Maybe I wouldn't have had any issues if I'd had a significantly over-capacity receiver from the start. But I'd still be wary of 1000lb bars for a TT similar to mine. You want the bars to flex, not be so rigid they stress what they're attached to. I do think EQ needs to revisit the jump from 600 to 1000.
