If I had to pick between the two, I'd take a trailer. At least it's something I own, I can make changes to it, I have somewhat of a yard. (though often you don't really own the property) while an apartment is basically a slight upgrade from living in your parents' basement. On the other hand some of the nicer apartments do have a nice view and there's a certain "coolness" factor to being in a high rise. But I imagine that gets old fast enough when you realize you can't even put a hole in a wall to run cabling or can't fix basic electrical stuff, etc.
It's crazy how expensive trailers are though! I always figured one perk is that they are cheaper than a house but I see some go for like 100k sometimes. Most of them are at least 50k. So while it is cheaper than a house, it's not by a very big magnitude.
One of the nice things of "trailer trash" places is that if people are actually allowed to leave cars on blocks on their front lawns and stuff and nobody bats an eye, then it means you have more freedom to do whatever you want without some bylaw officer giving you trouble. You can probably put up a wind turbine, garden, solar panels etc... whatever and people probably won't bother you for it.
That is the one thing that pisses me off is ridiculous bylaws that dictate what you can/can't do on your own property, or simply the fact that you don't even truly own your property. Being able to own land+mineral rights (most land does not actually come with mineral rights, if you find gold you can't keep it) and have control over it should be a right. As a person or even a business if I want to build a big garage or a warehouse or front lawn garden etc I should be able to do so without getting hassle for it or having to go through tons of red tape like permits etc. My city is now requiring to get a permit to erect temporary car shelters. This kind of red tape is ridiculous.
