Only so much cooling can be done without airflow. The vornado fans specifically funnel air from one end of the room to the other at like 15-30 feet.

Buy one, put it under your mini split, point it down the middle of your bus, and the whole thing will be a lot cooler.
TL;DR of the article: it's actually a feature that units are heated this much, because around the late 19th century/early parts of the 20th century, they came to the conclusion that fresh air was a good thing for indoor spaces, and keeping all windows closed made apartments way too stuffy. By the 1920's, building codes were changed with this in mind, and the way they would get people to open their windows was to provide more heat than necessary, forcing users to open windows.
I still highly recommend a read when you get a chance. It makes perfect sense, but of course, as things go, the info isn't passed down, people forget why something happens, and it's never revisited to improve the initial design.
This is the model of fan that I bought a few years ago. Not too big, and does a great job. There's an upgrade model from this one that's pricier but allows more fine-tune control if you're into that.
Vornado 630 Mid-Size Whole Room Air Circulator Fan
We’ve got one of these at the bottom of the stairs pointed up. It made a huge difference. 2400 square foot house with a loft at the top of the stairs that I use as my office. I went from sweating during the day to comfortable. Our bedroom is right off the loft so we keep the door open and it makes it bearable to sleep there as well.
Try a Vornado
It doesn’t work the way a typical fan does where you feel cooler when it passes you, it circulates the air in the room and makes the entire space feel cooler as a result.
I used it a ton when I lived in LA w no ac in 100F+ weather
If you don’t like the breeze and want to cool the whole room try one of these
I’m gonna get one before summer and from what I’ve read they cool the whole room better while also not blowing directly on you
Like others have mentioned, keep your place as dark as possible, and make sure you have ice in your dogs water bowl.
The Vornado helped me a lot in LA, it felt way cooler (maybe 10 degrees F) after having it on for about 30-60mins
This is the fan you want. I had one gifted to me by a fellow fan officianado. It is extremely loud and drowns out all other noise. It’s fan function works well too
I can't really help you with a clip fan, but I've had a Vornado 630 running on full speed in each of my tents for over a year now, with zero issues. They're very well made. I won't hesitate to buy more in the future.

First suggestion is to address the snoring... not only bad for you, but good chance it is terrible for his/her sleep. Tried nasal strips or positional therapy (ie, learning to sleep on stomach, etc) yet? Beyond that there's oral appliances or cpap machines or more invasive procedures.
As far as addressing noise, suggest ear plugs and white noise. IMHO best is decent mid-sized fan, vornado is my pick after trying a few (like this one). Also there are a bunch of white noise machines if you don't like the breeze... probs can find an app that does it over speakers if you want to try it out.
I have a Vornado fan in the mid/back of my room pointed to the ceiling. Room is 4'X4'X8' enclosure with two 300W LED lights (I'll get more watts in the future) and a 6" in-line exhaust with passive intake.
Circulates well, room is temp stable at around 82f degrees, humidity ranges from 38-60% depending on when I'm watering and misting. Tends to fall in the mid 40's most of the time.
The problem is your fan if you have a huge window and cannot equalize with the outside temperature. I recommend a getting a Vornado. The price is pretty steep for a fan but it will definitely be cheaper than a portable AC unit. I got one and never looked back - I'm sure you won't regret it. The build quality and operating volume of the fan alone will impress the hell out of you.
A fleet of Vornado fans are the best way to go barring AC.
I have one of these: https://www.amazon.com/Vornado-Mid-Size-Whole-Room-Circulator/dp/B000E5WAUO
Right of diagonal to the bike
The Vornado 630 or Lasko Pro are the top picks based on that thread.
I purchased both the Lasko blower and a Vornado 633, which can blow slightly harder than the 630 and is much more power efficient at low settings.
That lasko blower says it does 341 CFM, the vornado 630 does 363 CFM, the vornado 633 does 393 CFM. They're all in the same ball park.
Both fans provide a focused stream of air. At 3 feet, the vornado has an 8" diameter spot of high speed air. At 3 feet, the blower target area is about 6" wide and 12" tall.
I've been using the vornado for my torso and the lasko for my legs.
The Vornado 530 and 533 fans blow a good amount of air too, at 283 and 293 CFM, but are quite loud on high.
Yeah a fan is a fan, I use this one to block my roomate’s voice at night and it does a pretty good job.

Under 175$ (2000nt). In value. Think it would get through?
Maybe something like this could sit on the sill:
