So I chose to skip the exterior bike racks altogether. Bike transport is the main reason I selected the 2022 390MP floorplan.
The entry door is aligned with the mid Bunk room. There is a straight shot up the entry steps into the bunk room. I can roll bikes up the steps using a collapsible ramp. I roll the bikes up the steps into the bunk room and secure them with bungies and straps.
Later model years, the bunk room door is off to the left towards the kitchen. The bunk room door is not aligned with the entry door on these models. Because the entry door is not aligned with the bunk room door getting bikes into the bunk room is not as simple.
MY kids are older and no longer camp , I use the mid bunk room more as a utility room for bike transport and etc. I am seriously contemplating removing the mid bunk sofa to create easier access to the cabinets and to create more open floor space. I use the mid bunk room more as a toyhauler room vs. a bunk room.
The biggest plus of carrying the bikes in the bunk room is that they are not exposed to the elements and they don't have to be loaded and unloaded each trip. The bikes live in the RV! I have rather large heavy E bikes that are not the easiest to transport.
One thing I have begun to despise about RV'ing is set up and break down. I have become a bit psycho when it comes to taking an item out and using it because it becomes one more thing to break down upon departure! Using the Blackstone is an example unless I cook more than 1 meal on the Blackstone I'm not getting it out!
I apply that same principle to bringing along bikes. We ride our E bikes most every trip. We load and unload at the camp site, but we don't load and unload at home. Transporting bikes in mid bunk room has worked out very well for our usage.
I totally understand not everyone wants a mid bunk model, but for me it was the deal sealer for my 2022 390MP because of its ability to transport bikes inside the RV.
For the record I also have bike rack shown below that i use to bring extra bikes along for guests
