Thor buys Jayco

They (like every other takeover) will tell you everything will remain the same. Everything rarely remains the same for very long. Thor bought Jayco for 1 reason. To make more $$. Whatever needs to change to make that happen, will.
They can say Entegra is stand alone. But buying one now would be a gamble. In 2-3 years from now will it be valued as an Entega or just another Thor?

Dealers and suppliers will surely know the takeover happened. The average camper trailer buyer will probably not know or care as long as the monthly payment is what they can afford.
