Mine will be moving towards a full fun wagon in the next couple years as well. Put 20000 on it since April and it’s running strong. I’m excited to build it up a level to do more exciting shit. As it sits handled some alpine loop sections no problem last week next to the JLs on 37s and dirt of varying degrees of rocky every day since April.My skinny tall 33s on factory 5-stars didn't rub at all this past weekend at Lytle Creek. My alignment is factory neutral : cam eliminators at neutral/neutral and SPCs at D. No tubbing , no pinch weld mod.
I am planning to move the wheels forward by taking the rear cams to + (front stay neutral) and the SPCs to E right after I replace my ITREs
Regarding your shock question, I've been running tundra billies on 2ns notch and 620# coils for years without issue as a daily or weekend trail rig. I have not taxed them over endless woops in the desert but I suspect that's where reservoir shocks will have an advantage.
My rig is no longer my daily and is getting a used/rebuilt set of Icon 2.5s - it's becoming more of a camping wheeling weekend driver and I'm about to upgrade to 4.88 gears. One mod at a time.
