Curt Dual 2" Receiver Tube Adapter, 8" Extension Curt Accessories and Parts D-192
Can Curt Dual 2 inch Receiver Tube Adapter, # D-192 Be Used With Weight Distribution
I would like to use one of these to add a bike rack to my 2010 Buick Enclave with a Reese Mini 350 Fleetwood WD hitch towing a 2007 Fleetwood Popup camper. I want to know what effect does this adapter have on the overall tongue weight of the Reese WD as it is extended. I realize that the bike rack and bikes will add tongue weight, the popup tongue weight, and the Reese WD weight too?? This all added up to be the combined tongue weight?

The Curt Dual 2 inch Receiver Tube Adapter, # D-192, can be used to tow a trailer with the bottom receiver while carrying a bike rack in the top receiver. However, you will not be able to use it with weight distribution.
