After a long and extensive search for a bike rack that would meet our needs, we settled on a hitch receiver + bike rack setup on the A-Frame of our Airstream.
In our case, we wanted something that would just bolt on, which meant our options were limited to some installed on the A-Frame.
We used the Stromberg Carlson (CC-275) Bike Bunk

In combination with the Pro-Series 63123 Eclipse Black 3-Bike Hitch Mounted Bike Carrier

We had to reverse the direction of the bike mounting arm so that to bikes would be mounted toward the AS and not the Tow Vehicle (otherwise bikes would have touched the Tow Vehicle). Otherwise, no mods we necessary.
Also ended up getting CURT 22321 Anti-Rattle Kit because the bike rack was wobbly without it.

Great thing about this setup is that I can still open the front window guard and I can still access the generator mounted underneath.
Wanted to share the setup for others looking for a similar solution.
