Input on used Direct lift PRO 9-D

[buildingup]

Have the opportunity to purchase a used Direct lift PRO 9-D from my father in laws friend. I have the space for it but wondering if it is up to the job of lifting lifting my 08 Silverado 3500HD with a long list of aftermarket parts that surely added weight. Also, plan on purchasing a new F350 dually in the next 2 years to replace this truck so don't want to be undersized. I know its just under the capacity of the lift, just want to know if its safe and if people have first hand knowledge of these lifts.

I'm not sure about the width of the dually but my Direct Lift ProPark 9 has no trouble lifting my '99 F250 Ext Cab diesel. I do have to fold in the side mirrors...

I know the drive thru width is 92 1/4 which I still have to check to see if my truck will fit thru with the large offset wheels I have. Since this is a 2 post lift I am concerned about the arms bending or not being able to support the truck safely when I would be under it and working on it.
