I respectfully disagree about GG bags in fitting in the Moomba LSV. Below is a pic of the 03 GG LSV from one of the 2 NWL & 2 WWA events I pulled last year in Indiana. The key here is the playpen seating. The Moomba LSV has a walk-thur bow and not playpen. The front storage locker located in the walk thru will not accommodate a 1000lb bag but only the standard 400lb bag. No worries, most riders will put an additional 500lb on top of the front locker and then swap the rear 250's for 350-500's. It has a great wake!
The GG bags will work great for the Mob-V and XLV because they have playpen seating. GG bags will also work in Supra SSV because of playpen seating except when walk thru is ordered you have the same problem. I think this is an outstanding feature/benefit of the playpen found only in Supra/Moomba - you can trick out 2000+lbs without stepping on bags.
