I have a 2014 Palomino pop up and am looking for a way to take our 2 e-bikes with us. The bikes weigh about 70 lbs each. Our tow vehicle is a 2019 Dodge Grand Caravan. There are folding bike racks on the roof of the trailer but they don’t look like they would hold our bikes very secure and it would be difficult to get them Ont the roof of the trailer. Our trailer was originally a rental from an RA dealer and they had installed roof racks a to hold 4 bicycles, they are basically a trough for the wheels to sit in and a fold up arm that clamps to the frame of th bike. I am aware that I should not put a rack on the back of the camper. Any solutions or ideas would be greatly appreciated.
