Trying to take bike and a trike at the same time does present a challenge.
After looking at all the options and not wanting to have 2 bike racks and having them stick way out in the rear.
I opted to get a Swagman 4 bike rack from Camping World
That way I could have the bike on first then the Trike on last with the arms going thru the frame

On Edit. I use a cross bar on the Woman's bike to make it ride level, it makes it so much easier to load and carry.
