Nothing too major with mine. 2012 2910BH. Some leaks from the flush tank hoses. Had to reinforce one bottom bunk and the jack knife sofa. Slide was pretty far out of whack when we got it. Just needed to adjust the tensions/cables. I've found lots of screws stripped out our not tight enough. The hose clamp on the fresh water connection was not tight enough from the factory and when the tank was full it would leak. Lots of little quirks but again nothing huge. Like any other TT or RV keep it maintained and it'll be fine. You'll have to get use to the extra 20-30 min for hook up and unhook rituals. I always envy the RV that pulls up next to us at a camp, puts on the parking break and hits the electronic levelers and calls it camping. But then when they are stuck at camp or have to deal with pulling a little car, I don't feel as bad. The best part is my TT was $24000 new and the same floor plan in an RV would $80k and up. Also No engine, No transmission, No $200 tires. Etc Etc Etc.
