The slats allow the air to remain "hugging" the curvature of the profile, and the vortex generators will prevent the "boundary layer" to separate from the rear of the profile, giving you a smoother ride at high speeds, spoilers are over rated in that you will need to be at a speed above 80 mph to be of any benefit.
I think seeing the benefits of slats and vortex generators on a teardrop trailer is optomistic at best. I'm sure the effects would become really noticeable only at speeds above, say, 140 knots indicated but I do agree with your comment on spoilers.
I'd save my money, not fuss with slats and vortex generators, and buy some "lead weights" and mount them to the undercarriage of the trailer for any desired additional stability. As a benefit, the lead weights would help with fuel economy when going downhill. I would, though, ensure the tow vehicle and trailer's brakes were operating correctly.

Not if you make them large enough! But then aerodynamic drag becomes a problem...
This issue can be minimized by doing the calculations, determining the angle of attack where l/d max occurs, calibrating your angle of attack meter/gauge to same, and continously monitoring your angle of attack meter and maintaining approximately 14 units during all approaches. Never had a problem using this "approach".
