Morning Sparky,
What your asking for is a little unrealistic. Is your current setup too heavy to be reliable. Yes. Do you want to hear that....No. Have you proven otherwise....Yes (which is great by the way). I think more people are too busy worrying instead of going out and doing. By the sound of it you have been busy doing. (Again great)
Affirmation is great, but I don't think that gets you the answer you want. "Dude your Wrang is SiCK!" Did that help?
If your only looking for YJ experience this may not be the correct place. I think it is and would never suggest otherwise, a wider pool of experience is always better.
You obviously have apprehensions about your setup, since your looking for opinions. I have never broken a 35, but I have seen several break (axle, housing and gears), and seen countless broken ones in my wrecking yard experiences. Nothing as heavy as yours though. You can be heavy and never break, however its the exception, not the rule.
Have you thought about converting the rear to ff using d44 ends and trussing the housing, easy and relatively cheap. Would address the inherent d35 weaknesses.
As for me. None of my rigs have been as extensively equipped as yours, but my trips are shorter
FJ60 stock axles 3" on 33's 5900 ready for the trail never a break
W200 crew short d44/d60. 4750 empty 6100 ready for the trail
Ramcharger d60/14bolt 7890 ready for the trail broke everything at some point (except housings ;-) )
86 cj7 4500 ready for the trail spring over on stock axles with 35s, broke both axles and currently going through 1 tonification with the axles from the Ram.
