Quoting my own post with a quick update. This Icon suspension system combined with these tires exceeds expectations. Have had truck on multiple trails in Utah, Colorado and New Mexico. Have had rear wheels in the air and front wheels in the air and traveled washboard roads, rocky hills, deep mud, water, sand, etc. No extreme rock crawling, but this 'Max' version goes everywhere I need it to for basic overlanding.
Handles equally great on the road up to north of 95mph with full load in the vehicle. The adjustability of the dampening is great and offers a wider range of firmness than I expected.
At this point the only thing working against it is the length for short switchbacks, but I never expected 'everything' from it. Very capable even without lockers.
I'd say the only downside I've seen is the springs are a bit soft with a trailer on the vehicle. But the extra length of the 'max' may be playing a role in the sag I see.
MPG over 2100 miles of flat and mountains with varied terrain sits around 16 to 16.5 MPG.
Would 100% buy it all again exactly like this.
