Serious go with the Sturdy Safe- 3/8" construction

Go with the inswing so you can't get locked in......
I have used both...
Got a 2012 GL350 that needs help. Swapped out the particulate filter and Def tank, but having issues getting my full power back.
Anyone know a guru? Prefer to stay away from the dealer.......
