We have decided to upgrade the HTT to a fully enclosed TT and are interested in the Outback Terrain 250TRS. The advertised specs are a shipping weight of 5483 and a tongue weight of 585. My gut feeling is that this is about the maximum I'd want to tow with the TV. Does anyone think this is a bad idea?
The actual value for your TV can be found on the receiver's label.
Assuming max TW of 910# and typical TW% of 13% means your loaded TT weight could be 7000# without exceeding the receiver's rating.
A TW of 910# and a properly sized and adjusted WDH would result in a vertical load of about 910*0.8 = 730# applied to the TV.
Assuming the allowable weight of TV occupants and cargo is 1600# (actual value is found on label located on driver's door edge or pillar), you would have about 1600-730 = 870# available for occupants and cargo, including the weight of a WDH and any other after-market items installed on the TV.
Depending on how the TV is loaded you also might be near or over the rear GAWR.
As others have mentioned, the best way to predict how much TT you can tow is to load the TV as it would be loaded for camping, including about 100# for the WDH, and measure the axle loads.
Then we would have a better basis for offering advice.
