I'm trying to figure out a solution for the bike rack too. I have a 2023 AIM 15bh with 1 1/4 hitch receiver. I also
had a Yakima RV trailer rated rack and I have 1 eBike - 50 lbs. I hated the rack so I returned it. Very inconvenient and cumbersome to use in many ways. And the ramp is too steep with the rack on this trailer, the way the wheels go on the outsides of the wheel trays, I had the bike fall off a few times while trying to hold it with one hand and secure it with the other. And the pin, the straps, the spring knob, are all a pain to use. Lots of broken fingernails, bruises, scrapeals, etc. On the 1 trip I took using the rack, it was bouncing all over the place. There's a little bit of play in the hinge which translates to lots of bouncing while driving. I ended up strapping it to the ladder - not a great situation long term, but it worked for the rest of my trip.
So now I'm in search of another bike rack solution. Luckily I only have 1 ebike to deal with, but it's a little too long and cumbersome for my 5' truck bed with shell. It can work in a pinch, but not great for taking the bike in and out often, and takes up all my truck cargo space. And it would be nice to be able to bring a 2nd bike if I have a friend alongz or for when the grandkids get older.
I'm not sure if the hitch rating of 150 lbs is only because of the 1 1/4 receiver or the hitch bracket itself. But it would probably be more convenient to have a 2" received welded in instead of the 1 1/4. This was a dumb design by Grand Design since I don't know that there are any 1 1/4" bike racks that are travel trailer rated. I had to use an adapter to a 2-in receiver to insyallnthe bike rack. And before people comment on the wobble factor because of the adapter, the bike rack had a threaded bolt to eliminate any play into the 2" receiver, and I used an anti-rattle device on the adapter. That part didn't move. That 1/4" or so of play in the hinge translated to a couple inches of up and down movement on the bike rack itself, which put lots of pressure on the whole hitch when bouncing down a bumpy highway or in a parking lot full of potholes. And I used the inner track of the 2 bike rack to keep the bike closer to the trailer.
I'm thinking about using an aluminum cargo rack or motorcycle carrier (light weight) with no hinge and having a 2nd receiver welded onto the hitch and a bar welded onto the rack so I have 2 points of entry for more stability. I've seen some people do that for carrying motorcycles. Then I would also have some brackets added to the hitch to be able to remove the cargo rack and insert it upright against the trailer for when I want it out of the way (rather than a hinge to fold it up since this seems to be a bounce point). I haven't talked to a welder about it yet, so not sure how that will work out. But that's the best option I've come up with so far, after searching every RV rated bike rack I could find. The lack of RV rating on the rack or the combined weight of the bike and rack and the 1 1/4" receiver are the limiting factors. Then you can add bike wheel chocks or trays, and/or use motorcycle straps to secure the bikes. It would be pretty much a custom RV bike rack.
There's also a company making a bike rack meant for off-roading with trucks or jeeps. But it's pretty expensive ($1400 + $100 shipping) and has a long lead time to order it, and I'm not sure it will be any better. And still needs a 2" receiver.

I'd love to hear what other ideas or solutions people have for a bike rack for this trailer model.
