Don't buy that van. But you probably will - LOL... Even if you get it smogged today, in a couple of years it's gonna be your problem to smog it.
I am from where you are (Ex Californian - socal) - UCI is a decent school but the bottom line is unless you are getting a science degree (MIT) or an advanced business degree (Stanford e.g.) where you went to school is gonna be highly irrelevant among the "good" second tier schools.
LA is the land of commuting at excruciatingly slow speeds. I lived in a cab over camper when I was in college. I parked up in the Hemet/Riverside area (for free) and commuted 40 minutes to school - in the camper.
You've sunk the costs into the RV. I am with the others except that I would move as far away as it took to find a long term place and get a beater/commuter car.
Otherwise sell the RV and look for a room. But even that's not a good option. My nephew went to UCD (Davis - near SFO) and had 3 roommates to rent a 2 B/R - they double bunked two in each room. You also might plug into some kind of deal like that. I am betting for sure there is a student assistance group that has a lot of resources on housing. Interestingly (or not) when my brother (his dad) moved back to Yorba Linda my nephew transferred to UCI.
I am encouraged by your determination and your stubbornness to walk the path less followed. Someday you'll be 61 and be able to tell all the molly coddled kids of 2063 how rough you had it while living in a van to get your degree - LOL...
I'm exploring all the possibilities. Including selling my RV, but I'm listing it for $29k and no one is even asking.

I don't really want to sell this RV unless they pay enough money to build the same one. As in 2 years, once I'm out of Irvine, both LA and the SF Bay Area are RV friendly. My future plan is to live in the RV in my backyard and make an Airbnb. Combined with my salary, I should pay off my mortgage fast.
$25k is the absolute minimum required to build one like this.
Parking the RV where I can and commuting is probably the best way to go. I have been told by residents that people park RVs on the streets of Santa Ana and North Tustin for long periods of time without issue. I checked the law, which says it's not allowed, but it doesn't seem to be enforced. However, the biggest problem I have with sleeping in an RV is the noise. Both of these places have noisy streets for RV parking, and Santa Ana is not safe. I can't afford a break-in and to lose everything. The solar panels and mini-split are asking for problems.
Rowland Heights seems to be the best candidate; low crime and quiet, and the bottom line is that, as an unincorporated community, I even found a dead-end street with no houses facing the street, which is critical. I didn't find any rules against parking and living in RVs.
I would have to get a commuter car, though, and according to Google Maps, I would have to leave before 5 AM to get to school in 30 minutes.
Regarding buying a commuter car, I can buy a very creepy car for $2000, a 2015 Mirage for $5-7000, or a 2013 Prius for $12000. If I buy a 2013 or newer car, I can still drive an Uber, which means if funds are low, I can solve it just by driving more Ubers.
The advantage of the Prius is that I can sleep inside it if I need to.
The gas mileage is actually only a little better than the Mirage.
But on the other hand, do I really have the time to drive an Uber? I'm not even sure I could survive at UCI. Also, If I stop spending on random stuff and everything goes well (which means I get paid for the internship and get financial aid), I will need to do no Uber.
I'm planning to go to Rowland Heights as early as possible. I can still adjust over the summer if problems arise.
