Going from pop-up to full size trailer, even a short one will introduce you to front aerodynamic resistance at highway speeds as well as side sway forces.I definitely like the idea of having a reasonable size vehicle both for towing and everything else, I am very happy with my combination and would be happy to encourage you to upgrade, but..........
SUVs are tricky and design nuances matter more than just size. I checked the Trailblazer specs and unless you have the SS version I don't really like it. The engine is quite good though but good news end just here. However, 4- speed transmission and 3.42 rear end almost never will work well. You will be able to pull at third on flat surfaces but even modest incline will drop you to second and you engine will hit the redline while struggling to maintain speed. Soft suspension and high sidewall tires will be unable to control sway even with good setup. Tahoe with V8 is clearly better, but well maintained used ML our Touareg with right outfit is much more fun overall in my opinion
