Welcome. I "WAS" a rookie too 8 months ago when I purchased my 308BHS as a surpise anniversary gift for my wife. This site has helped tremendously. Since May 1st, we've logged about 44 nights in the camper and have traveled all over our home state of Michigan as well as our maiden long distant trip to Disney's Fort Wilderness.
Knock on wood, we haven't been back any Keystone dealer yet and I plan to keep it that way. There is an outstanding recall on our Bullets with regards to A/C wiring on the roof top unit. It's a 5 minute fix at the dealer if you can get an appointment. I'm planning on taking it in prior to de-winterizing in the early spring.
Here's a
compilation of mods I've done to my unit since April. A Maxx Air fan will be my next mod this spring.
I hope you're having as much fun as we are with ours. Again, Welcome!
