We bought our 2013 GT 378 just a year ago. After an initial bout with FR on repositioning the mirror on the drivers door, we thoroughly enjoy the coach. Have put about 8K miles on it; planning a 10K Alaskan trip this summer. Would suggest the "cheap handling fix", CHF, discussed on FR forum as well as the rear trak bar and front super-steer. Makes a world of difference on the highway when being tossed about by winds or semis.
Enjoy!!
