If 50 pounds is going to make the difference in the TV and trailer tongue weight, then I think maybe the the TV is under rated for the job.
I crossed the CAT scales with my 2007 Mercedes ML320 CDI on the way home with the new empty 25FB International Serenity. The weights on the MB axles were fine.
The dealer service manager stressed that this year's car was rated for only a 5,000 pound trailer. The empty trailer weight was about 6,100 pounds. Fully loaded for camping, the trailer came in at 6,960 pounds. Now the front axle was overloaded and the GVWR was exceeded. I could have massaged the weight off the front axle to the rear axle and then not have exceeded each axle rating, but the GVWR would still have been overloaded and the drive line capability was exceeded by nearly 40%.
I elected to not trash this expensive car and continue to use it as my economical daily driver. I purchased the 2012 Dodge Ram 2500HD diesel where no GAWR axle ratings would be maxed out and the trailer weight would be under the maximum rating.
I crossed the CAT scales with the new Classic model 30 very lightly loaded for an overnight and the truck had a Honda 2,000 watt generator and a 5 gallon full gas can in the bed. No axle ratings were exceeded and the total weight was 16,940 pounds.
