Unladen weight

My KW 680 is the same. I hover around 10700 and 11200 on the steer all the time.

 

You won’t add much at all, if any, to the steer with your 5th wheel back depending on where all the way back is on your truck. You don’t really start throwing a lot of weight into the steer until your 5th wheel gets up forward of the center of your drives.

 

That's about where my truck is, wish my father wheel slider wasn't seized as #### so I could slide it back a notch or 3.

 

Pressure washer, penetrating oil, a big bar, and maybe a big hammer.

 

Tried that, let er soak for a few days, no luck. It was froze when I bought the thing 6 years ago.

 

You should be fine. My new T880 runs almost identical to you. I run my 5th plate barely to the rear of center on the drives. At full drive axle weight I am allowed at 38K I don't exceed 12.5K on my steers.

 

Try it dry. If you can’t get red dust flying everywhere with an air nozzle and an air chisel, save your effort and find another slider rack.

 

It'll be fine on the old turd for awhile. It needs a lot of work and money that I'd rather just put in my 359.

try cranking trailer high then dump truck air so it has weight pulling on it .. sometimes that with penetrating oil will break it free overnight.
