Tahoe 3.42 axle 5.3 Vortex and 5,000 lb Jay Flight 26BH

That Jayco is not 5,000# as that was the dry weight which is meaningless. Normally loaded you will be in the 6,000#+ neighborhood with a potential of up to 7,500#. Even at just 6,000# you will have 780# of tongue weight and definitely need a serious WDH (add another 100# for that). You need to check the payload of your TV as you are probably pushing the envelope with nearly 900# of tongue and hitch weight. Good luck. :C
