Ford vs Chevy for Rockwood and Jayflight;
Ford vs Cadillac if it's a Rockwood versus Eagle. As far as "trailers" go.
Rockwood and Jayflight both seem nice and owners +/-'s about the same from what I hear.
The Eagle is more of a premium product (and price) though in many ways, and should be looked at as such if you are comparing it to a Rockwood. Not saying the Rockwood is negative in any way, just is not the same in standards and options.
IMO from what I have come across, the Rockwood line is a great all-around starter trailer with a good reputation and cost. But many 2nd time buyers go for the Jayco line when they look to upgrade.
