I'm not sure where you are suggesting that I should put gussets?
I would put the gussets at all 4 corners of the outside frame to prevent lateral shearing. While under there, it wouldn't hurt to throw in a few in the angles between the outer frame sides and the crossbeams.
Pardon the horribly cheap drawing, but here's what I mean. Your trailer frame in blue, and the gussets in red:

And this is what I'm talking about, just a triangle piece welded into the corners:

Now I'm just an amateur/hobby welder so this is just my 2 cents. But I do believe this will add a lot of resistance to lateral frame shearing/flexing and wobbling if you do hit some rough roads and will make it much more rigid. It also takes some load off of the welds so you're less likely to break one (god forbid!). I think it's worth adding the extra 2 lbs of weight for extra piece of mind

The trailer frame I'm looking for, or might end up building, will also have an X underneath made out of angle that'll run from corner to opposite corner which should also prevent the frame bending/bowing, and also prevent twisting. But that's a whole 'nother level of being picky
