TV aside, if you want strong, start by getting a TT that doesn't have a Lippert frame.
Northwood builds their own frame and has them independently certified to their "off road" standards. The same frames are used on Outdoors RV units.
Lance uses a
BAL Ultraframe. A limited number of other makes/models also use the BAL frame like the Jayco Whitehawk. I see that Norco Industries (BAL) is now making a new generation of their frame called the
NGX Frame. Both use huck-bolts for fastening and have almost no welding. You could always call them and ask for a list of makes and models of TT that are using them.
I'd also get a TT with shock absorbers - either as standard item, optional upgrade or having them custom installed (not hard to do). In addition, install Dexter EZ-Flex equalizers c/w heavy duty shackles and wet bolts.
