Hi Frank,
First of all, I'm not an expert on tubular spaceframe chassis, so I don't know if corrosion is an issue there or not. My guess is that due to sufficient wall thickness and quality of steel, corrosion is not too much of an issue overall - other forum members may chime in here.
I'm not an expert on corrosion either. My basic understanding is that you need water, oxygen and unprotected steel for corrosion to take place (at least that is the type of corrosion I have in mind).
So assuming your horsehoe is welded airtight with no pinholes etc you have a sealed space and corrosion should not be an issue. However, if it is not 100% airtight, you will end up with water inside the horsehoe (from spray when driving in the rain or just from condensation over the seasons). Once you have water inside and no drainage hole I would assume you will have corrosion sooner or later and depending on the wall thickness and quality of your sheet metal this will cause problems in the future.
Long story short, I would drill some drainage holes in the bottom of the horseshoe (lowest point) and also drill some holes in strategic areas to spray some sort of anti corrosion wax into the horseshoe. The holes will also allow ventilation and moisture to get out.
As you are also from Europe, you are probably very familiar with rusty cars.
Not sure how fluent you are in German but here is a good overview of body cavity sealing products ..... https://www.korrosionsschutz-depot.de/rostschutz-und-lacke/hohlraumschutz/
Sorry for the long answer.
