I do have a solution for you, provided you do not have a factory trailer hitch. In order for this hitch bike rack to fit on your vehicle, you will need a hitch extender if you need 11" of space. Unfortunately, anytime you add a hitch extender you reduce the maximum tongue weight of the trailer hitch by 50%. The factory trailer hitch of your 2021 Ram ProMaster 3500 is 220 lbs. Adding the hitch adapter will change the maximum tongue weight of the trailer hitch to 110 lbs. The weight of your hitch bike rack and the bikes you are carrying cannot exceed this weight. You will not be able to carry the RockyMounts BackStage Bike Rack for 2 Bikes - 2" Hitches - Wheel Mount, part # RKY10002, and two ebikes with this setup, you will exceed the 110 lbs.

The solution will depend on what type of trailer hitch you have on your 2021 Ram ProMaster 3500. I did some research and your 2021 ProMaster 3500 will have a maximum gross tow weight between 6,410 lbs and 6,910 lbs. Your maximum tongue weight will be between 641 lbs and 691 lbs. You will need to get a trailer hitch. My recommendation is the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2", part # C13207. The maximum tongue weight of your vehicle is less than the maximum tongue weight of this trailer hitch. You will have to adhere to your vehicle's maximum tongue weight.

The next thing you need to add is the RockyMounts Hitch Extender LS w/ Hitch Pin and Lock - 2" Hitches - 8" Long, part # RKY10011. This hitch extender will add 8" on the trailer hitch. Your new maximum tongue weight will be between 320 lbs and 345 lbs. Then you will be able to use the RockyMounts BackStage Bike Rack for 2 Bikes - 2" Hitches - Wheel Mount, part # RKY10002. This rack weighs 60 lbs.
