IMO, many TT suspensions (leaf springs, axles, tires) are "at the edge" of their max weight loads. They are sized based on 13% weight on the trailer tongue (on the TV's hitch). Thus, not needing the full weight load numbers. Ya, good way to keep the lawyers away during its warranty time period. But, very risky when loaded heavy and/or across rough driving conditions. Thus, reason for many snapped leaf springs and/or axles out of alignment (which wears out tires much faster).
For "average" paved road and normal speed gravel road driving, I think "wide track" (re: axle being 1-2" longer) has no great benefits either. IMO, its more of a marketing thing. Especially since most people "slow down" on rougher driving conditions. It's like having auto vehicle tires distance 1-2" wider. I cannot feel the difference. LOL!!!
If into rougher road (but NOT off-road) driving conditions, I would simply buy a pre-owned TT and with money saved (from going 1-2 year pre-owned), upgrade its leaf spring packs to "next size up", upgrade its axles to "next size up", install after market shocks and install Dexter EZ-Flex yokes. re:

Hope this helps...
