Looks like your limiting factor is going to be the tongue weight. Trailers should have approximately 12% or more of it's loaded weight on the tongue to be stable. At the low end of 12% would mean a loaded TT weight of 5000lbs, dry weight would likely have to be under 4k to achieve that unless you are super light packers. You'll struggle to find a 25' TT that light.
Also, is 25' the box size or overall length? If it's the model number it will be pushing 30' overall which is long for an SUV with a very short wheelbase.
Too light on the tongue and too long for the TV can lead to control and sway issues.
