Just know that most ALL of the OEM's use the lightest TV as their basis for their MAXIMUM tow/haul ratings.
Nature of that beast driven by Marketing to folks who are ignorant (uneducated) on the matter. AKA...King of the Hill bragging rights that folks post here most of the time as an absolute
Back to the OP
Your decision.
If you have desire for a new, albeit lower class TV than your current TV...go for it
But, know and understand you are stepping DOWN in TV class
Use their OEM ratings and understand how that system works
Of most importance are the actual weights of your new setup. The limiting factor of all TVs of any class are the RGAWR among the other ratings
Most all of the weight put on/in any TV is generally going on the rear axle. As in most cases, the drivers rear door edge is at the center line between the front/rear axles...and the bed is behind that center line.
Good luck !
