Recommended MORryde Pin Box For A 2018 Grand Design Reflection 303 With A Lippert 1621 Pin Box


Hi, I have a 2018 grand design reflection 303 GVWR 11995, 1621pin box ,does not say HD On the pin box says 15500 GVWR, The size MR64VR says up to 11.5k, what size for my trailer? Thanks


Helpful Expert Reply:

MORryde # MR64VR, # MR74VR, # MR84VR all have a GTW of 18,000lbs but each have a finetuned spring capacity for a smoother ride which is why you see 11.5k listed for the # MR64VR.

Since your 2018 Grand Design Reflection 303 has a GVWR of 11995 and you're probably adding 1000-2000lbs in equipment, water, etc. you're going to want the MORryde Cushioned 5th Wheel Pin Box for 11.5K to 14K Trailers w/ Lippert 1621HD # MR74VR. This model will be an upgrade from the factory 1621 pin box on your fifth-wheel trailer by dampening road shock and reducing back-and-forth chucking for a more relaxed towing experience. Unlike air bags, the internal rubber spring requires no maintenance.
