That sounds just fine.

Your build plate will show the tag only rated for 6000 lbs.

happy coaching!

Tag axle regulator should be set at 35#

What's a typical drive axle and steer axle airbag pressure? 80 psi?

Depends on the weight and the bags. With the old style double convoluted bags my 8 ran 55 rear 65 front. After installing the new rolling lobe bags all the way around it bumped it up to 65 rear 70 front to maintain same ride height. My guess would be possibly even more pressure for my DL3 since it's quite a bit heavier, but maybe not since the bags are a bit larger.

I have the new rolling lobe bags all the way around in my 102C3. I'm wanting to bypass the leaky leveling valves and go completely manual with my pressures and wanted to know approximately what they should be set at as a baseline

Scott the book should give you the ride height, just air it up until you reach the number in the book. I did the manual air level controls on the last one. For this one I am going to install the HWH air levelling  system. It maintains all the original system and ride height control valves for travel, just locks them out for levelling. It's actually a pretty neat system. Has it's own little compressor for maintaining level while parked, fully automatic.
