Where to put bikes?

I have front bunks with a side door that you can access and put two bikes upside down (wheels up) on the bunk and two bikes go on the roof of my truck. I too use a step stool. My set up is a Thule fork mount and two wheel carriers behind the bikes. I could install 4 trays on the truck but the kids bikes are so easy to put in the camper and I don’t even fold up the bottom bunk. We have done some serious MTB riding over the years especially before kids so using a roof rack is second nature on any vehicle profile. The key is grabbing them low and holding them sideways and stand them up once you’re ready to set them in the trays. Removing is almost the same as you slightly lift and allow them to fall towards you holding them sideways as you back away or step off the ladder. A little practice and you will have no problems. Personally I would keep them off the back of the camper. I would opt for the Stromberg Carlson set up on the tongue if I did not use the roof of my truck. That rack is a solid platform for a good hitch or rack with trays either upright or fork mount.
