Having a competent, experienced sandblasting business do large items is
probably going to be a lot more practical.

First, only the rusted areas need sandblasting. Removing paint with blast
media is costly and impractical, when paint stripper will do the job that's
needed.

If there is original paint on major areas, it's better to use that as a
primer coat, as many home shop refinishing jobs won't adhere as well to bare
steel as a factory finish, which was probably baked on.
Scuffing/sanding most original factory paints (not epoxy types) properly
prepares it for refinishing.

I'm aware that media blasting provides an excellent surface for primer
adhesion, but only under the proper conditions. A primer coat (or cold
galvanizing coating) should be applied as soon after blasting as possible
(the same day), and again, under favorable conditions of temperature and
humidity.

Choosing a brand of refinishing products that offer users a complete
Refinishing Guide is a wise choice (even if the guide has to be purchased).
Guides contain needed personal protection, safety and preparation
information.
A good guide will provide instruction about which products are used for
different applications, and should be like a short training course in proper
use of the various products (mixing, temperatures, air pressures and much
more).

I am wanting to do some sandblasting in the future. (Like a trailer
frame). Most pressure blasters with a large nozzle take a huge amount
of air. I dont have 3 phase in my garage. Is it possible to run one
compressor and another one into one line going to the blaster?
