Thanks All! I have much to learn about the mechanics/maintenance of a rig, so all info is appreciated! I'm thankful for the low hour tip--would have thought low hours meant good generator! Also, I'm so grateful for the tip on purchasing a used rig, to know I should take maybe an hour "test drive" to insure the "genny" is in good condition. Still leaning towards the class B; I can keep it in my driveway and won't have to worry about storage. LOVE this website! I'm on the road tomorrow (in my little Nissan), heading back to NY, and will begin my real search over the weekend. So far, I'm just doing an online search. Will keep you posted!
(Oh, I also figured out I can use the "search" on this site--entered "onan" and found many previous posts. I'm just not that computer savvy, but looks like I'll be learning that too! For instance, love the "smilie" guys!)
