We bought our HTT at the Atlantic City RV show back in March of 2005. It was delivered a few days before Memorial Day. The salesman at the dealership told us that they were turning out 17 HTTs a day at the Forest River factory at that time. The only real problem we had with it was a leak at one of the outside storage doors. They didn't caulk the bottom of the cut out. However, I've seen plenty of RVs from different manufacturers that don't caulk the bottom of the cutout.
Our Motorhome was bought at a dealer. It was built in March of 2009. It had a handful of problems, but only 2 of them were Jayco issues and minor at that. The other problems were issues with things Jayco didn't manufacture, like the converter/charger and the genset.
