We have a 2024 Passport that has a 1.5-inch receiver on the back that has a listed capacity of 300 pounds. We want to carry two 56-pound bikes. We have a Kuat rack that is rated for the weight and rated for use with an RV, but it requires a 2.5-inch receiver. We tried a 1.5 to 2.0 adapter with an added "u" clamp to tighten the connection but there was a great deal of movement. The bikes looked like they were bouncing on the end of a diving board. We tried a 2.0-inch bumper clamp on receiver with similar results. Has anyone added a 2.0-inch receiver by bolting or welding it to the trailer frame? Any other ideas? We currently carry the bikes over the truck tailgate, but this is difficult to load and takes up bed space. We would prefer to use the bedcover and carry some things in the bed out of the weather.
