Well with the new Dodge 3500 DRW 4x4 the fiver has to be lifted. the springs are on top of axle already. Found a company that makes blocks to lift it more. Bigger tires are not an option as they will not clear unless fiver is lifted. Anybody else had to resort to this?

Sure, lots of members have done that. There is an excellent post here that was recently done and explains, with pictures, how he lifted his rig. Many others have done basically the same thing or had dealer do it.

I helped a buddy lift his 5er. We build a subframe out of box steel 6" tall. (maybe it was 8")
Anyways, we cut off the hangers, welded up the frame extension to the bottom of the existing frame plus boxed it in by connecting left to right side, got new hangers and welded those up and then reinstalled the shackles, leafs and axles. (Tandem axles) Works great! Oh, we had to extend the brake wires due to the extra lift.

It helps that my buddy is a machinist and we had all the equipment to lift and block the 5er as we did the work. I learned a lot!!

You can also reverse level the truck. Then add airbags to level the truck after pin weight is added

I wouldn't use spacer blocks. I'd build a subframe as they said.

Lifting the trailer will add a lot of lateral stress to its frame. Weld in a substantial X member between the rear axle shackle hangers to negate those forces.
Its the 'wag the dog' flexing effect as well as fatigue in your frame that could lead to frame failure of the spring hangers breaking away from the frame.

How much lift do you need? You could put on something like Lippert's Correct Track and get a couple inches of lift. I put on the Morryde SRE4000 and got about an inch of lift.

Lifting this way puts more side stress on the hangers. Also the main frame rails can twist, so cross bracing is important. Finally any added side stress added with normal stress at the three hangers increases the risk of main frame cracking. For all these reasons a fully boxed subframe is the better solution as has been recommended. Just depends on your risk tolerance.

The Lippert Correct Track will give you 2" of lift, I added it to the TT so I could fit LT tires.

Common problem with new trucks and older trailers. Good thing you bought the dually, SRW sits higher yet. There have been some excellent posts on this forum the last couple of years with pictures showing solutions. Make sure you have enough headroom so you don't get too tall.
