Well.....
I should have done this a long time ago! It is a little high in back, but I think the springs will settle a little. Also there is no water or anything in the camper. So far I only drove a few miles but it feels great, like it was designed to carry the camper. Surprisingly I left the rear shocks on the softest setting (remember they are valved 20% firmer than normal). No bouncing or rocking, I could see maybe running the shocks on 2 or 3 but it is SO much better. Cycled the suspension in a ditch some, and it just works so much more evenly. Dropping a tire off of a full curb was just smooth and uneventful. Nothing rough, no bounce. No noise.
As the old man emu springs started to sag a bit, more weight had been resting on the timbrens. I felt like the truck bucked more. I think these was similar to what people experience with too much air in airbags. It creates an odd pivot point in the frame if carrying too much weight. It feels much better with weight on the springs.
For now I've just installed the superbumps from wheelers off road. I may dig out the other hardware and install the shorter softer timbrens that came with the allpro kit.
The springs have ten leafs, the front mount is a double wrap around the bushing. Anti friction pads between the leafs (aside from the bottom two or three short ones). I also bought new u bolts and nuts/washers. The threads on the other set are in great shape but I figured it was a good idea anyway. Piece of mind.
Here is the rear setup at full droop. Roughly 10.5" from the frame to the metal mount of the bump stop. The shocks are 10.3" travel, so the rubber bump stops could nearly fully compress and the shock won't bottom out.
The whole setup, complete with old man style shock boots!
Like I said, a little high in back. But the idea was to still have a little forward rake once the water tank is full, gear is loaded up etc. I think it's perfect. Still fits in the garage fine.
Tomorrow I need to wash the truck, it's filthy. I also need to pull the flexible solar panels and figure out how I'm going to mount the new panels.
