Question:
I need to replace my rear bumper on my 2019 Forrest River FR3 33DS What are the differences between Part Number: MNT78VR Part Number: MNT43VR Is it just the finish? Will these fit my Motorhome? Do they come with the Brackets? Thank You

Hey Ed, yes the only difference between the two RV bumper part numbers you mentioned is the finish. The part # MNT78VR is a paintable aluminum finish and the part # MNT43VR is a glossy black finish.
This will fit your Forest River and it does come with the needed install hardware.

Hey Ed, how did the replacement bumper work out on your Forest River FR3? It’d be great to hear if the fit and finish matched what you were expecting. Your update could make it easier for others choosing between those two bumpers.
