Video Transcript for Review of Mount-n-Lock RV Cargo Carrier - MNT45ZR

Hi everyone, Steven here with etrailer.com. Today we're looking together at our AddaBumper Extension Plates for your Mount-n-Lock HEAVY-HAUL'R RV bumpers. These are a 14-hole application. You're gonna get two of these plates with 12 bolts and nuts. Now these bolts are actually self tappers, and yes, these self-tapping bolts are specially made to be used on the nuts as well after you've got 'em all in place on the installation. So, these will extend your RV's frame to then properly mount your RV bumper.

And again, it works with the Mount-n-Lock HEAVY-HAUL'R replacement bumpers, sold separately here at etrailer.com. They're made with durable steel. They have been black powder coated on the finish, so they're very strong and very reliable. They're nice and thick. About three-eighths inch of a thick to be exact.

And again, you're going to drill into the RV frame with this included hardware. And again, they are self tappers. So it's a 14-hole bolt-on installation with the included hardware. Folks, that is gonna wrap it up for our quick look together. I'm Steven, thanks for watching.

  • Will Mount-n-Lock Heavy-Haul'r Bumper Fit 2026 Grand Design Reflection 24RL
    Hi Dana; I don't have a way of knowing what kind of frame is on that Reflection but I'm sure the Mount-n-Lock Heavy-Haul'r # MNT49ZR can be installed. The AddaBumper Extension Plates # MNT45ZR aren't required, they make it t easier to mount the bumper and give you more room for bumper mounted accessories. I also cannot tell you if it will interfere with the hitch or not. More than likely the hitch hangs down far enough that the bumper won't be in the way. Since you haven't bought it yet...
