Blows me away how axles can be out of alignment from factory but I've seen a few and had one myself.
Can't believe an axle jig isn't used as this would enable perfect alignment 100% of the time and prevent unsuspecting owners from issues such as sway and blowouts.
My 2020 trailer with Lippert frame had front right axle forward 1/4" and sure enough tire was warmer than other 3 via temp gun, not much but enough to warrant my investigation.
Easy fix with leaf sprung frame.....4 bolts and a tape measure but unacceptable from factory.
