I have specifically read scale weights for a cruise-ready 25 on the trailer of around 8,700#. That makes me think that you might be able to squeak by if you kept things very light. But have you checked the various specific ratings on your tow rig (more than just the overall "towing weight")? I find that oftentimes the rear axle weight is the first to go over (especially since tongue weight is magnified by the lever arm distance), and that in reality I could never really tow the rated "towing weight." So even the "up to" 8,200# may not be realistic (especially if your truck is not empty). Maybe it is, but don't just assume is all I'm saying. My van was rated to tow "up to" 7,500#, but when towing 4,500# with gear and a passenger, I was pretty close to the various limits in real life (scale weight). The "up to" might have been achievable if I had removed the van's interior, all gear, and my passenger.
Of course if you are in the "squeaking by" range, then you have to decide if you are comfortable with that. I could potentially go either way depending on my use case scenario (six blocks in flat Florida to the ramp and back once per year vs. two-plus-full-gear going cross country being opposite scenarios, for example).
One reason I went with a 22 (amongst others) is that I could comfortably tow it with my 3/4 ton van (then) and small RV (now). At around 4,400# all up it's about half the weight of a 25. OTOH, if I had definitely wanted a 25 then I would have sold the van and bought a tow vehicle to match that load.
