It is perfectly normal for the brake lights to flash when using the warning lights (hazard lights) after installing the Curt 2-To-3-Wire Tail Light Converter # C56196 on a vehicle like your 2017 Dodge Challenger. There isn't a way to resolve the issue due to how the signals come out of the converter box. view full answer...
The weight of the cargo carrier as well as the weight of the cargo is included in the tongue weight for a hitch on your 2014 Dodge Challenger. For example, the Curt Trailer Hitch Receiver # C13236 has a 350 lb tongue weight, so you would add the weight of the cargo carrier plus the weight of the luggage on the carrier to get the tongue weight.
To maximize the amount of gear you can carry I recommend a lightweight aluminum carrier, the 49x22-1/2 Curt Cargo Carrier for 2" Hitches # C18113.
