As to Goodyear stepping up.......
Had a G614 that was 3 1/2 yrs old blowout (boom......large hole them separation)
thread slapping around torn out waste tank drain piping (dirty shower time for those behind us), tore up wheel well skirting, side marker light, under side of slide out.
Called Goodyear.....filed claim.
Bought new tire (sent copy of receipt)
Had repairs done at factory (quickest/easiest to get it done)
Goodyear reimbursed me for tire ($312)
Goodyear paid factory directly for repairs. ($2500)
Biggest issues was having to haul torn up tire to tire shop. Difficult to load into truck with all the thread flapping around and the steel cords trying to stab me.
