Dimensions Of Roadmaster Dual Receiver Hitch Adapter RM48BQ

Updated 05/26/2026 | Published 05/16/2026

Question:

Hello, what is the distance from the hole in the solid stinger to the beginning of the receiver? What is the distance from the top of the solid stinger to the bottom of the upper receiver? Also, what is the depth of the receiver in-line with the solid stinger? I recently purchased a Gen-Y multiple receiver but the receiver in-line with the stinger is not deep enough for my receiver hitch to and I want to make sure I have enough depth on this model before trying it. Lastly, what is the depth of the upper receiver from the hole to the back nearest the vehicle? See attached photo for dimensions Im looking for. Thanks!

Hey Jeff, thanks for reaching out, and thanks for attaching that photo - that makes this easy! I went and grabbed one of the 068-6 Road Master Dual Receiver Hitches # RM48BQ from our warehouse and got all the measurements you were wanting. I edited the picture you sent to show them all. Please note the top receiver is open on the back. Hope this helps!

What do you plan to use the top receiver for?

Thank you! I am hoping to use this in the 6” “lift/raise” format, using the lower receiver in-line with my truck’s receiver for our small pop-up tent trailer and the upper receiver for a bike rack. Both the rack and pop-up together are well below my truck’s towing and tongue weight capacity.

@JeffD Ok nice! It'll work great for that! Just keep an eye on your total tongue weight and make sure it stays under that 400 lb limit and you'll be good to go.
