We have had two of our three RV's Jayco's. Very pleased, I don't agree that they are entry-level units. Our experience with Jayco both for warranty and overall build has been very good.
We currently have a Class C 2003 Jayco Greyhawk, of course on the Ford 450. They have been around a long time, have a great selection and a good following.
We prefer the motorhome over a trailer at this point, as we do a lot of traveling, stop and go and site seeing. And a class C is great for that, easy to stop anywhere and have what you need, stay a quick night and move on. It is also nice that we can flat tow our jeep, or our ATV's for weekend fun.
At some point we will move onto the fifth wheel set up, but not until our highway miles and traveling are a bit over.
