One reason I chose to purchase a slightly used TT vs. new was knowing I would need to replace the tires, mattress, etc. before our very first trip... IMO TTs should roll off the assembly line ready to handle 3,000+ mile trips & 30+ days of camping without serious issues.
I understand that 3rd party components fail, even quality ones. However, the RV industry is full of intelligent people who are well-aware of the FACT that cheap China Bomb tires fail. They also know that they could quickly fix this issue for just a couple hundred dollars per RV but they choose not to.
IMO until TT manufacturers start placing better tires, mattresses, etc. on NEW TTs, I will buy slightly used TTs saving 30%-50% vs. new. In my case we saved enough to buy new tires, replace the mattress, add fans, and still have plenty of money left-over to replace all of the major appliances, etc. should they fail.
So many families jump into RVing before they factor-in the costs... IMO it's easy to find a gently used TT at substantial savings. Just inspect them VERY carefully for water damage & avoid folks who owe more than their RV is worth. My 2 cents...
